Question

When equal volumes of 0.1 M solutions of HCI and NaOH are mixed, the total number of ions present will be approximately

(A) twice as great as before mixing.

(B) the same as before mixing.

(C) half as great as before mixing.

(D)10^-7 times as great as before mixing.

(E) 10^-14 times as great as before mixing

Answer 1

HCl and NaOH are broken down as ions in solution

H⁺ + Cl^- + Na⁺ + OH^- = Na⁺ + Cl^- +H₂O

The number of ions have halved. The correct choice is (C)
