I am going to see which liquid- coke, water, or vinegar, will clear rust the fastest. I am doing this to make old and rusty nails look better and become stronger. This will result in better buildings and projects. It will also help recycling. When we throw out nails, rusty or not, we waste iron and steel. This project might help that problem. I believe vinegar will clear rust the fastest since my family sometimes uses vinegar to clean our jewelry. I will do this project by dropping rusty nails in water, vinegar, and coke.
For this project you need many things. The first things you need are three plastic cups. The rust may stain on the cups so I recommend plastic ones. You want three nails covered in rust. All the nails must be the same size. You need a camera to take pictures of the changes that occur to the nail. Also, you need to get water, coke, and vinegar. It doesn’t matter what type of vinegar but I recommend regular coke. I would also appreciate it if you use tap water. The last thing you need is paper and a pencil.
You can find the cups and the cok...
Baking Soda and Vinegar: Limiting Reactant Lab Background The limiting reactant of a chemical reaction is the substance that places an upper bound on the amount of product that the reaction can produce. The limiting reactant places this upper bound because the reaction must stop once all of the limiting reactant is consumed. If the relative amount of reactants is altered, then the limiting reactant may change accordingly.
The objective of this experiment will be to combine various substances, liquids and metals, and to observe their behavior when they are combined. The types of reactions observed shall determine the nature of these reactions: physical or chemical.
Investigate the source of the soil and stain to help you determine the most effective poultice for stain removal. Look at the color, location and the formation of the stain for clues. A stain that looks like a brown splotch, found in the kitchen near the coffee pot, is likely a coffee stain, for instance, while a reddish colored stain near a plant container or metal object might be rust.
The purpose of this experiment is to determine the effects, if any, that freezing Gatorade has on its conductivity.
As you may know, when you mix baking soda and vinegar there is a big reaction, but have you ever wondered how this reaction happens? Well in order to find out how it happens you will need to know the elements that make up baking soda and vinegar. You will also learn why these elements are where they are on the periodic table and what is released during the baking soda and vinegar reaction.
Prepare the nails by removing any old nail polish present on the nail. Clean the nails with hand sanitizer.

That teeth will rot faster in Coke than milk or water. That there will be a slight difference between milk and water substances on decay levels.
Problem:Investigate the rates of the chemical reaction between various amounts baking soda reacting with vinegar.
What does happen when you mix vinegar and baking soda? While your immediate answer may be "it fizzes and turns white" there is much science behind the concept. You will find that what it "looks like" is not nearly everything behind what really happens. Baking soda and vinegar form a completely different compound (when two or more elements combine; broken down by chemical changes like adding energy as heat or an electric current), which has it’s own properties. From the particle model of matter to the way that a chemical reaction is represented in an equation, the answer is definitely complicated.
The purpose of this project was to discover how the pH level affects corrosion rate. The hypothesis was if the pH level affects the corrosion rate, then the lower the pH level is quicker the corrosion rate would be. This will happen because liquids below the pH level of 7 possess stronger acidic attributes. The effect of pH level on corrosion rate was determined by depositing a copper penny in each of three plastic cups, and then three different liquids by their pH levels, were assigned to be displaced into each cup formulating a chemical reaction to be observed. The results collected during this investigation contradicted with the intended result, this experiment was conducted to determine corrosion rate; Dana Puti Vingear (pH level: 4.5) 4 2/3 days, Tropicana Orange Juice (pH level 3.88) 6 1/3 days, and Sprite (pH level: 3.4) 8 days. The results showed that the hypothesis was refuted. This happened because the preconceived idea was that the liquid with the lowest pH level; Sprite, would have the quickest corrosion rate. Dana Puti Vinegar had the quickest corrosion rate proving the statement wrong, it was discovered that it contains ethanoic acid; acid containing twice the amount of carbon dioxide than a regular acid. To further understand this topic, future research could include; how does the amount of liquid incorporated affect the corrosion rate, how does the temperature of the liquid affect the corrosion rate, and how does the purity of iron affect the corrosion rate?
My hypothesis is that orange juice would be better then Gatorade, because I believe that it would hold more electrolytes. Some material that I will need to figure this out is Digital multimeter, Alligator clip leads,
The materials in our project will consist of various items. The main materials used for the experiment are female pig livers, basic beer, hard liquor, red wine. We will also need four buckets to put the alcohol and the livers inside. A knife, and T pins are materials we will need
