E . M . F . of the given below cell will not be zero because P t ( H 2 , 1 a t m ) / 0.1 M H C l || 0.1 M acetic acid /( H 2 , 1 a t m ) Pt

Options

  1. AThe p H of 0.1 M H C l and 0.1 M acetic acid is not the same
  2. BAcids used in two compartments are different
  3. CE . M . F . of a cell depends on the molarities of acids used
  4. DThe temperature is constant

Correct answer

A. The p H of 0.1 M H C l and 0.1 M acetic acid is not the same

Step-by-step solution

The pH of 0.1 M H C l and 0.1 M acetic acid is not the same, because H C l is a strong acid so its p H is less and C H 3 C O O H is a weak acid, so its pH is more.
