State whether 1 M solutions of the following salts in water would be acidic, basic, or neutral. You must fully explain your answer to earn full credit. (3 points),

FeCl3

BaI2

NH4NO2

Homework Answers

Answer #1

1) FeCl3 . it is acidic

because it is the salt of weak base and strong acid .so acidic property is dominent.

cation involve in hydrolysis : Fe+3 + 3 H2O -------------------> Fe(OH)3 + 3H+

H+ ions released by Fe+3 so it is acidic

2) BaI2 it is neutral . it is the salt of strong acid and strong base. so it is exactly neutral .

Ba(OH)2 strong base + HI strong acid

3) it is also amost neutral . because it is the salt of weak acid and weak base

weak acid HNO2 and weak base NH3
