Which one of the following statements is not true?

Which one of the following statements is not true?

Options

  1. ApH+pOH=14\mathrm{pH}+\mathrm{pOH}=14 for all aqueous solutions
  2. BThe pH\mathrm{pH} of 1×10−8M1 \times 10^{-8} \mathrm{M} HCI is 8
  3. C96,500 coulombs of electricity when passed through a CuSO4\mathrm{CuSO}_4 solution deposits 1 gram equivalent of copper at the cathode
  4. DThe conjugate base of H2PO4−\mathrm{H}_2 \mathrm{PO}_4^{-}is HPO42−\mathrm{HPO}_4^{2-}

Correct answer

B. The pH\mathrm{pH} of 1×10−8M1 \times 10^{-8} \mathrm{M} HCI is 8

Step-by-step solution

An acidic solution cannot have a pH>7\mathrm{pH}>7.
