What mass of copper will be produced from 0.5 Faraday of electricity [Cu=63.5].

What mass of copper will be produced from 0.5 Faraday of electricity [Cu=63.5].

A. 63.5g 

B. 31.75g

C. 15.88g

D. 7.95g

Let's solve this step by step.

We are asked: Mass of copper produced from 0.5 Faraday.

Given:

• Atomic mass of Cu = 63.5 g/mol

• 1 Faraday = 1 mole of electrons

• Copper is monovalent in electrolysis (Cu²⁺ + 2e⁻ → Cu), but we need to check carefully.

Step 1: Determine moles of electrons

0.5 Faraday = 0.5 moles of electrons (by definition).

Step 2: Use electrochemical equivalent

Copper electrode reaction:

Cu^{2+} + 2e^- 一> Cu

• 2 moles of electrons deposit 1 mole of Cu.

So, moles of Cu deposited:

moles of Cu =  Moles of electrons 2 = 0.5/2 = 0.25 moles
Step 3: Mass of copper

Mass = moles * atomic mass = 0.25 * 63.5 = 15.875 approx 15.88 g
