Question

Separate acid and alkali radical from the following compound

and write them with their charge.

(a) CuSO4 (b) CH3COONH4 (C) MgCl2

(d) KNO3 (e) Ca(OH) 2
​

Answer 1

Answer:

(a) CuSO4

Ans=) acid radical = SO4 - -

alkali radical=Cu++

(b) CH3COONH4

Ans=)acid radical = CH3COO-

alkali radical = NH4 +

(C) MgCl2

Ans=)acid radical = cl-

alkali radical = Mg++

(d) KNO3

Ans=)acid radical = NO3-

alkali radical =K +

(e) Ca(OH) 2

Ans=)acid radical = OH-

alkali radical = Ca ++

Answer 2

Answer:

1. CuSO4 = Cu+, SO–.

2. CH3COONH4 = CH3COO+, NH4–.

3. MgCl2 = Mg+, Cl–.

4. KNO3 = KN+, O–

5. Ca(OH)2 = Ca+, OH–
