If the concentration of OH^ - ions in the reaction Fe(OH)_3(~s)...

If the concentration of OH−\mathrm{OH}^{-}ions in the reaction Fe(OH)3( s)⇌Fe3+(aq)+3OH−(aq)\mathrm{Fe}(\mathrm{OH})_3(\mathrm{~s}) \rightleftharpoons \mathrm{Fe}^{3+}(\mathrm{aq})+3 \mathrm{OH}^{-}(\mathrm{aq}) is decreased by 14\frac{1}{4} times, then equilibrium concentration of Fe3+\mathrm{Fe}^{3+} will increase by

Options

  1. A4 times
  2. B8 times
  3. C16 times
  4. D64 times

Correct answer

D. 64 times

Step-by-step solution

To maintain the constant value of Kc\mathrm{K}_c, the concentration of Fe3+\mathrm{Fe}^{3+} ion will increase by 64 times.
