The reaction which is taking place in nickel- cadmium battery can be represented by which of the following equation?

Question

Q. Given the cell:

C d (s) | C d (O H)_{2} (s) | N a O H (a q, 0.01 M) | H_{2} (g, 1 b a r) | P t (s)

with

E_{c e l l} = 0.0 V

. If

E_{C d^{2 +} | C d}^{o} = - 0.39 V

, then

K_{s p}

of

C d (O H)_{2}

is:

Answer 1

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

Answer 2

The reactions involved in Nickel-Cadmium battery are,

Answer 3

At Anode:

C d_{(s)} + 2 O H_{(a q)}^{-} \to C d (O H)_{2 (s)} + 2 e^{-}

Answer 4

At cathode:

N i O_{2 (s)} + 2 H_{2} O_{(l)} + 2 e^{-} \to N i (O H)_{2 (s)} + 2 O H_{(a q)}^{-}
