Question

Q.4- Write answer is one word/sentence of each;
(ii) Write the concentration of the hydrogen ions in pure water?​

Answer 1

Answer:

In pure water, the hydrogen ion concentration, [H+], equals the hydroxide ion concentration, [OH-]. These concentrations can be calculated from the equation for the ionization of water. The pH of pure water is 7, the negative logarithm of 1 X 10-7. A neutral solution is one that is neither acidic nor basic.

Answer 2

Answer:

Pure water is considered to neutral and the hydronium ion concentration is 1.0 x 10-7 mol/L which is equal to the hydroxide ion concentration. So the pH is the -log of the [hydronium ion].
