(See attached file for full problem description) --- The Nernst equation is the most important equation in electrochemistry. It is defined as follows: Where is the standard reduction potential of the reaction is the gas constant is the temperature (in Kelvin) is the number of moles of electrons transferred in ...continues
(See attached file for full problem description)
I have used a battery and water treated with washing soda to separate water into hydrogen and oxygen in class. Can someone explain in simple terms what happens to change the water into two gases?? I understand that why there is twice the hydrogen as oxygen, but the Chemistry gobbledygook has me confused.

Reaction and reaction kinetics when calcium carbonate is added to solution of water and acetic acid?
Help!! See attached problem statement. An unknown (but assumed relatively small) amount of calcium carbonate is added to a 1000L solution of water and acetic acid which exhibits a pH of 4.0.The CaCO3 is used to raise the pH to 5.0 but more specifically is to create the chemical reaction such that when the solution is heated, ...continues
