A steady current of $1.5 amp$ flows through a copper voltameter for 10 minutes. If the electrochemical equivalent of copper is 30 $\times 1 0^{- 5} g$ coulomb $^{- 1}$ , the mass of copper deposited on the electrode will be.NEET 2007

Options:

Answer:

Solution:

Given that $I = 1.5 A t = 10 mm = 600$ secand $z = 30 \times 1 0^{- 5} g coulomb^{- 1}$ According to faraday first law of electrilysis $m = Z I T = 30 \times 1 0^{- 5} \times 1.5 \times 600 = 0.27 g$
