the concentration of HNO3 in a solution that has a pH of 3.4?

What is the (a) H+ ion concentration, (b) pH, (c) OH- ion concentration, and (d) pOH of a 0.001 M solution of HCl?

What is the (a) [H+], (b) [OH-], (c) pH, and (d) pOH of a 0.002 M solution of HNO3?

What is the concentrations of HOAc and OAc- in a 0.2 M “acetate” buffer, pH 5.0? The Ka for acetic acid 1.70x10-5 ? sorry but given pKa wasn't related to this question can you solve it again??

Describe the preparation of 5 liters of a 0.3 M acetate buffer, pH 4.47, starting from a 2 M solution of acetic acid and a 2.5 M solution of KOH. (pKa 4.77). can you solve it again because there was change in q
