C u 2 + ions reacts with F e 2 + ion according to the following reaction C u 2 + + 2 F e 2 + ⇌ C u + 2 F e 3 + At equilibrium the concentration of C u 2 + ions is not changed by the addition of

Options

  1. AC u 2 +
  2. BF e 2 +
  3. CCu
  4. DF e 3 +

Correct answer

C. Cu

Step-by-step solution

C u 2 + + 2 F e 2 + ⇌ C u + 2 F e 3 + For this reaction at equilibrium the concentration of C u 2 + ions is not changed by the addition of Cu as it is solid. So its molar concentration is always taken as unity.
