The Relative Formula Mass of an Unknown Acid
1.1 Aim of the experiment
The aim of the experiment is to find the relative formula mass of an
unknown acid in an acid solution that I was provided.
1.2 Introduction
I was provided with a solution of a monobasic (monoprotic) acid.
Monoprotic acid is an acid that contains only one hydrogen atom. I was
to determine the molarity of the acid by titration with a sodium
hydroxide solution, and...

result, I will get the value of 63.27.
Final experimental result = experimental value + the overall apparatus
error
= 62.37 + 0.9 = 63.27
% difference between experimental Mr and value of likeliest value
= (62 / 63.27) × 100% = 100% − 97.99% = 2.01%
4.3 Conclusion
From the titration process I found the molarity of the sodium
hydroxide solution and the relative formula mass of the unknown acid.
With further calculations I identified the correct formula of the
acid. The experiment was done without any major mistakes and
complications, although there were some minor mistakes in calculations
due to the apparatus used. This could be solved in another experiment
by using more appropriate equipments. It will reduce the overall
percentage error and minimize the mistake.
One of the best methods for determining mass in chemistry is gravimetric analysis (Lab Handout). It is essentially using the the mass of the product to figure out the original mass that we are looking for. Thus the purpose of our experiment was to compare the final mass in our reaction to the initial mass and determine the change in mass.
2.57e-4 mol myristic acid x 228.37 g/mol myristic acid = 0.059 g of theoretical myristic acid
Possible sources of error in this experiment include the inaccuracy of measurements, as correct measurements are vital for the experiment.
The sought to determine the effects of mixing various levels of acids and bases to see which combination would have the most explosive reaction, and measure the resulting pH levels. I did this by testing an assortment of different pH levels of acids and bases, mixing them together and measuring the results. Most of the experiments resulted in a pH neutral solution, except for the Sulfuric Acid and the Sodium Hydroxide. By far, the Sulfuric Acid was the most explosive, followed by the Citric and Acetic acid.
One possible source of experimental error could be not having a solid measurement of magnesium hydroxide nor citric acid. This is because we were told to measure out between 5.6g-5.8g for magnesium hydroxide and 14g-21g for citric acid. If accuracy measures how closely a measured value is to the accepted value and or true value, then accuracy may not have been an aspect that was achieved in this lab. Therefore, not having a solid precise measurement and accurate measurement was another source of experimental error.
Also, it had provided enough trials to find an accurate volume of Ca(OH)₂. The data collected gave enough information to find the mol of H⁺ ions which equaled the mol of OH⁻ ions because of neutralization. Furthermore, this helped to find the concentration of OH⁻, which helped find the concentration of Ca²⁺ because every 2 OH⁻ ions have one Ca²⁺ ion. That is why the concentration of Ca²⁺ was half of the concentration of OH⁻. With these two concentrations the Ksp was found which was 2.92 x 10^⁻⁵. The actual Ksp is 5.5 x 10^⁻⁶, therefore, there is a big difference. In fact, the percentage error is 431%. This could of happened because of some sources of errors in the
Purpose: The objective of lab four was to use the website Late Nite Labs to determine mole-to-mole relationships and empirical formulas in chemical reactions. Combining and/or heating various compounds, observing the reactions and then calculating the moles revealed the balanced chemical reactions.
There are four conditions that are associated with acid-base imbalance. Disorders that result from changes in the partial pressure of carbon dioxide (PCO2) in systemic arterial blood are respiratory acidosis and respiratory alkalosis (Tortora, 2014). Disorders that results from bicarbonate (HCO3) concentration are metabolic acidosis and metabolic alkalosis. When the lungs cannot remove all of the carbon dioxide the body produces, a condition called respiratory acidosis occur. Respiratory acidosis has high level of PCO2 above 45mmHg and a blood level that drop below a pH of 7.35. Normally when you breathe, you inhale oxygen and exhale CO2. Excess CO2 in your
To conclude this lab, we learned how to calculate the mass volume percent of acetic acid in a vinegar solution using stoichiometry learned in unit 2 and how to conduct a proper titration lab.
Chemistry is not used only in a lab environment, but it is used for every aspect of life. One way to look into a more in-depth view of chemistry is to apply it to a hobby, or something that may personally affect your everyday life. One of the biggest parts of my life and my main hobby is flying. Ever since I was little, I have always wanted to become a pilot. I am currently working towards my private pilot’s license and I am also attending the U.S. Air Force Academy starting in June to study aeronautical engineering. Since flying is such a large aspect of my life and is important to me, I wanted to break it down into an aspect of chemistry. I chose this topic because flying is very important to me and it will continue to be a large part of my life as it will end up being my career in the Air Force. Not only will researching the topic of aviation fuel help me to become a more knowledgeable pilot, but it will also help me to understand more about chemistry and expand on the concepts we have learned this semester. Chemistry is extremely important to planes and pilots. One of the most obvious aspects of flying that deals directly with chemistry is fuel. Without fuel, aircraft would not be able to run. The molecular formula of fuel and the combustion of fuel are just some parts that play into how fuel makes an aircraft run.
and the volume of acid. By doing all this we will make sure that it is
The purpose of this lab was to calculate the ratio of moles of water to anhydrous salt by measuring the mass of the water lost and the mass of the remaining anhydrous salt. Ultimately being able to use the ratio to determine the formula of the original hydrated salt. My hypothesis was: If we determine the correct ratio of moles of water to moles of anhydrous salt, then we will find that the water and the anhydrous salt are equal parts in the hydrate because it does not appear to contain a lot of water. This hypothesis was rejected by data.
The prevailing system of body composition is primarily focused on model, where the body is composed of two diverse compartments: fat mass (FM) and fat free mass (FFM). Indirect and direct anthropometric measurements can be used to assess nutritional status of particular individual and to determine body composition and distribution of body fat. Different methods have both adventages, as well as limitations. Furthermore, they might provide sources of measurement error. (Ulijaszek, 1999; Willet, 1998; Gibson, 2005)
Defying Robinson Appleby 's agreement to never teach a Negro how to read, Mamed, the overseer with a raised cane, proposes Aminata an offer which she cannot decline. Being the overseer in Appleby 's plantation, Mamed 's duty is to ensure that the plantation is properly functioning while Master Appleby is absent. In fear of being disciplined for divulging the prohibited prayer, Aminata recognizes Mamed 's humanity as he murmurs, “Allahu Akbar”. With Mamed 's offer to Aminata to tutor her how to read and write, perhaps if “Georgia was teaching [Aminata] how to survive in the land of the buckra, but maybe Mamed could teach [her] how to get out” (Hill, 216). Mamed 's teachings start with the pronunciation of Aminata 's name to eventually forming a sentence with basic, common words to the rules and procedures established in Appleby 's hacienda. As Aminata 's fear of Mamed eventually subsides, Aminata apprehends the idea of Mamed being a different man, “like a man who was willing to teach” (Hill, 218).
There is also the potential of human error within this experiment for example finding the meniscus is important to get an accurate amount using the graduated pipettes and burettes. There is a possibility that at one point in the experiment a chemical was measured inaccurately affecting the results. To resolve this, the experiment should have been repeated three times.
