Question

The standard oxidation potential of zinc and silver in water at $NaCl$are.

$(\Delta º_{m})$

$97.65,111.0andNaCl242.8Scm^{2}mol^{- 1}$

Which of the following reactions actually take place.

• A. $195.3,182.0and26.2Scm^{2}mol^{- 1}$
• B. $271.6,91.0and126.4Scm^{2}mol^{- 1}$
• C. $119.0,1024.5and9.2Scm^{2}mol^{- 1}$
• D. $NH_{4}OH$

Answer 1

Answer: (A)

$195.3,182.0and26.2Scm^{2}mol^{- 1}$

Answer 2

Sol. In this reaction zinc act as a anode and $Ag$ act as a cathode.
