Question

Negative plate of Edison accumulator contains,

• A. $Ni{\left(OH\right)}_2$
• B. $P{b}_3{O}_4$
• C. $CuS{O}_4$
• D. $Fe{\left(OH\right)}_2$

Answer 1

The correct option is D

$Fe{\left(OH\right)}_2$

Explanation for the correct option:

Option (D):

Edison Accumulator:

1. The basic components used in the Edison accumulator are nickel hydroxide $Ni{\left(OH\right)}_2$ as the cathode, iron hydroxide $Fe{\left(OH\right)}_2$ as anode and potassium hydroxide as the electrolyte.
2. We add Nickel sulfate and ferrous sulfide to the active material.

Hence, option (D) is the correct option.
