change of pH in urine I'm looking to lower the pH of a urine solution from 12 to 7. I'm planning to do it in 2 ways. First is to use a strong acid such as HCl. Secondly, using vinegar, a weak acid. However, I am having troubles calculating the pH in both methods as it other chemicals in urine such as ammonia may react to it. Since it's a theoretical experiment, can I just assume that the acid would only react to water? But how will I do it either way?
Not knowing what concentrations of the other chemicals that are present, it is impossible to do a theoretical calculation. The only way to do this would be experimentally.
