Question

Ni-Cd સંગ્રાહક કોષમાં ચાર્જિગની સંપૂર્ણ પ્રક્રિયા કઇ છે. (A) Cd + 2Ni(OH)48) ► CdO26) + Ni(OH)2(s) +H2O(1) (B) CdO6) + Ni(OH)2(s) +H2O(1) ► Cde+ 2Ni(OH)3() (C) Cde) + 2Ni(OH)3(6) ► CdO (6) + Ni(OH)2() + H20 (1) (D) CdO2(8) + 2Ni(OH)2 + 2H200) ► Cde) + 2Ni(OH)4(5) 2​

Answer 1

Answer:

Correct option is

A

Cd+NiO

2

+2H

2

O→Cd(OH)

2

+Ni(OH)

2

Due to their low internal resistance and the very good current conducting properties , Ni-Cd cells can supply extremely high currents and can be recharged rapidly

The reactions involved in Nickel-Cadmium battery are,

At Anode: Cd

(s)

+2OH

(aq)

−

→Cd(OH)

2(s)

+2e

−

At cathode: NiO

2(s)

+2H

2

O

(l)

+2e

−

→Ni(OH)

2(s)

+2OH

(aq)

Overall reaction: Cd

(s)

+NiO

2(s)

+2H
