Fundamentals J 5 Neutralization

Postby Christina Cen 2J » Mon Dec 04, 2017 1:50 am

For the reaction in 5b with (CH3)3N and HNO3, why does it not produce water and a salt? Is it not a neutralization reaction?

it could be that (CH3)3N is a weak base while HNO3 is a strong acid so since they are not both strong they will not produce a water and a salt. Although it still should be somewhat neutralizing since it is an acid-base reaction

You can't completely neutralize a weak acid or base because the conjugate acid/base will affect the pH. The conjugates are in equilibrium with the acid or base they came from, and this will affect the pH of the solution. For example, acetate in water, the neutralization product of acetic acid, will pull protons from the water and raise the pH, acting as a base. Also, this reaction in problem 5 cannot make water because (CH3)3N does not have an OH to create water.
