Question

Determine whether each of the following salts will form a solution that is acidic, basic, or pH-neutral. NH4ClO NaClO C2H5NH3Br Fe(ClO4)3 KCl

Answer 1

NH4ClO    = salt of weak base and weak acid ,so the solution nature depends on the Ka and Kb values .If Ka > Kb then solution is acidic. If Kb > Ka then solution is basic)

NaClO    = salt of strong base and weak acid. so the solution is basic.

C2H5NH3Br = salt of weak base and strong acid. so the solution is acidic.

Fe(ClO4)3 = salt of weak base and strong acid. so the solution is acidic.

KCl = salt of strong acid and strong base. so the solution is neutral.
