PLEASE READ: I know the answers, they are marked in bold!! I just would like someone to explain how to find them!!!!!!!!!!

12. Which of the following statements concerning aqueous solutions of salts is FALSE?

A) For any salt of a strong acid and a strong base, the pH will be about 7.

B) For any salt of a strong acid and a weak base, the pH will be <7.

C) For any salt of a weak acid and a strong base, the pH will be >7.

D) For any salt of a weak acid and a weak base, the pH will be about 7.

25. Which of the following salts will form a basic solution?

NaBr

Ca(NO3)2

NH4Cl

NaCH3CO2

Al(ClO4)3

part 1 )

A salt of a weak acid and a weak base produces a solution whose pH depends on the strengths of the acid and base which made the salt

part 2 )

NaBr is case of strong base and strogn acid

NaOH + HBr

Ca(NO3)2

is case of strong acid and strong base

CaOH2 + HNO3

in NaCH3CO2 is case of strong base and weal acid

NaOH + CH3COOH
