Question

6 of 10 Classify these salts as acidic, basic, or neutral. Acidic a Basic Neutral Answer Bank K₂ SO₂ NH ₂ Br NaN Ke LiCloy)

Answer 1

1) K2SO3: This is basic in nature. Because this is a salt of KOH & H2SO& and KOH is a strong base and H2SO3(sulphurous acid) is a weak acid.

K2SO3 ------> 2K+ + (SO3)2-

K+ = strong base

(SO3)2- = weak acid

K+ and (SO3)2- react with water and form KOH & H2SO3.

2) NH4Br: is acidic in nature. Because this is a salt of weak base(NH3) and a strong acid (HBr).

NH4Br -------> NH4+ + Br-

NH4+ = weak base

Br- = strong acid

NH4+ & Br- react with water and form NH3 and HBr.

3)NaCN: is basic in nature. Because this is a salt of strong base(NaOH) & weak acid (HCN).

NaCN ------> Na+ + CN-

Na+ = strong base

CN- = weak acid.

Na+ and CN- react with water and form NaOH and HCN.

4) KCl: is neutral in nature. Because this is a salt of strong base (KOH) and Strong acid (HCl).

KCl -----> K+ + Cl-

K+ = strong base

Cl- = strong acid

K+ and Cl- react with water and form KOH and HCl.

5)LiClO4: is neutral in nature. Because this is a salt of Strong base (LiOH) and strong acid (HOCl4).

LiClO4 ---------> Li+ + ClO4-

Li+ = strong base

ClO4- = strong acid.

Li+ and ClO4- react with water and form LiOH and HOCl4.

Hence, now we can write-

Acidic = NH4Br

Basic = K2SO3 , NaCN

Neutral = KCl , LiClO4.
