# Find the amount o

Given

Equivalent mass of silver EAg = 107.9 g

Current passed = 0.005 A

We know

1 F (faraday) is 1 mol of electrons

1 F = one electron (1.602 x 10-19) ×Avogadro's number (6.022 x 1023)

= 96,500 C of charge

Amount of charge required is 12 times of 6.023 × 1023 =

= 96500 C of charge

The Electrochemical equivalent of silver,

Where

E is the equivalent mass of silver

Agf is the amount of charge

Using the formula, from faraday’s law of electrolysis –

where,

m = the mass of the substance deposited on the electrode

z=electrochemical equivalence

i=current passing

t=time taken

we get:

So, 2.01 g of silver is liberated on electrode.
