C) The weaker the conjugate base. D) The weaker the conjugate acid. E) None of the above.Explanation / Answer
1. A substance which gives OH^- is called Arrhenious base.
NaOH ----------> Na^+ (aq) + OH^- (aq)
B. NaOH
2. A acid base pair differ one H^+ is called conjugate acid-base pair.
D. C2H3O2^-/HC2H3O2
3. H2Po4^- -----> HPO4^2-
acid conjugate base
A. HPO4^2-
4.A.CO3^2-
5.D.Co3^2- and BrO2^-
6.acid is weak it's conjugate base is strong
B. The stronger the conjugate base
