Have you ever wondered what happens when water and electricity mix? This research paper will discuss the physics behind how the pH of salt solutions changes when an electric charge is passed through it. There are many different avenues of exploration to take with the complex physics of this project all of which are unique and interesting. A salt bridge is a non-covalent interaction between two ionized sites. It contains two components: a hydrogen bond and an electrostatic interaction (Salt Bridges). The scientific term salt bridge has two different uses in chemistry. The original use is described as an electrically conductive gel union that is between two half-cells of a voltaic cell studied in the field of electrochemistry. The second …show more content…

One half of an oxidation reduction (redox) reaction takes place in each half-cell. Alessandro Volta demonstrated this basic principle by stacking zinc and silver disks that were separated by paper disks saturated in salt water in about 1800. The salt water was used as the salt bridge. By stacking several of these zinc-bridge-silver disk sets, he was able to pick up an electrical shock when he touched both ends simultaneously. A real battery cell had been constructed in 1836 by John Frederick Daniell, who used zinc and copper. A strip of each metal was dipped in a solution of its own kind of metal ion. The two strips were connected by a wire and the two solutions were connected by a porous ceramic tubing filled with salt water, which was the salt bridge (In Chemistry, What is a Salt …show more content…

The different properties of water allow it to be labeled as one of the most important substances for life on the earth, and most of it has to do with its chemical structure. Again, water is composed of two hydrogen atoms and one oxygen atom. The arrangement of these atoms is the property that makes water such a good solvent. Rather than being arranged straight across, the two hydrogen atoms are at a 104.5 degree angle, making the molecule appear as a silhouette of a cartoon mouse. This makes one side of the molecule- the oxygen side- able to be negative, while the other side- the hydrogen side- is able to be positive. Since water contains this unique makeup, it is often considered a universal solvent. Different substances from sugar, to salt, and also to acids such as vinegar are able to be dissolved in water. Oils and fats are not able to be dissolved in water because they have no charge and the water molecule is more attracted to itself than the fat and so it will pool to one area. Another of the interesting properties of water is that it contains a high specific heat. Specific heat is the measurement of how much heat it takes to raise the temperature of one gram of water that is one degree Celsius. Water is able to absorb a lot of heat without changing temperature, and so it has a high specific heat. This results in water cooling down and heating up much more slowly than the air surrounding it. Ice also contains an interesting
