The acid dissociation constant of benzoic acid is 6.5 x 10^-5. Therefore, the pH of the benzoic acid solution prior to adding sodium benzoate is:
pH = -log[Ka]
pH = -log (6.5 x 10^-5)
pH = 4.19
The pH of the benzoic acid solution is 4.19 which is acidic, but a weak acid.
A. soluble.
The are solubility rules that predict precipitation reaction.
B. both high energy and low energy waves
Answer:
there is one carbon atom and there are two oxygen atoms. So, in total there are three atoms.
