Acidic, basic, or neutral?

Predict whether aqueous solutions of the following compounds are acidic, basic, or neautral: (a) NH4Br, (b) FeCl3, (c) KClO4, (d) KClO4, (e) NaHC2O4



a) Acidic
b)Acidic
c)basic
d)neutral
e)acidic


What do you use to predict it?

Answer:
NH4Br from NH4OH + HBr ( HBr is a strong acid, NH4OH a weak base)

FeCl3 from Fe(OH)3, weak base; HCl, strong acid

KClO4 from KOH, strong base; HClO4; strong acid

from their derivatives;
strong + strong = neutral
strong acid + weak base ; acidic
strong base + weak acid; basic
