Question

Electrolysis of aqueous $cm^{2}mol^{- 1}$ solution produces.

• A. $cm^{2}mol^{- 1}$ gas at the anode
• B. $Na^{+} - 50.1,Cl^{- 1} - 76.3,H^{+} - 349.6,CH_{3}COO^{-}
  • 40.9,Ca^{2 +} - 119.0$ gas at the cathode
• C. $(\Delta º_{m})$ gas at the cathode
• D. $CaCl_{2},CH_{3}COONa$ and $CaCl_{2}CH_{3}COONa$ gases both at the anode

Answer 1

Answer: (B)

$Na^{+} - 50.1,Cl^{- 1} - 76.3,H^{+} - 349.6,CH_{3}COO^{-}

• 40.9,Ca^{2 +} - 119.0$ gas at the cathode

Answer 2

$2H^{+} + 2e^{-} \rightarrow H_{2(g)}$ at cathode.
