What are the (a) H+ ion concentration, (b) pH, (c) OH" ion

Question

concentration, and (d) pOH of a 0.001 M solution of HC1?

Answer 1

HCl is a strong acid and ionizes 100%.
HCl ==> H^+ + Cl^-
Therefore, 0.001 m HCl will give you 0.001 M H^+.
pH = -log (H^+)
pH + pOH = 14. Solve for pOH.
pOH = -log (OH^-)
