Answer to Question #66926 in Inorganic Chemistry for queue

Question

What if I have dissolved 10g of HA in propanol and I want to adjust pH by adding nitric acid, then will the particles react with acid in this case? I have a doubt that it might depend on the mass of particle.

Answer 1

HA will react with HNO3 only in the case when both acids are mixed together without propanol. The result will depend on which acid is stronger i.e. HA + HNO3 = A- + NO2+ + H2O (HNO3 is weaker) or HA + HNO3 = H2A+ + NO3-. In the propanol liquid medium pH of both acids will be lower to that in water environment.
