Question

The concentration of hydroxide ions is greater than the concentration of hydronium ions for acidic solutions. true or false

Answer 1

Answer: False

Explanation:

pH is defined as the negative logarithm of hydronium ion concentration present in the solution.

$pH=-log[H_3O^+]$

If the solution has low hydronium ion concentration than hydroxide ion concentration, the pH will be high and the solution will be basic. The pH range of basic solution is 7.1 to 14

If the solution has high hydronium ion concentration than hydroxide ion concentration, the pH will be low and the solution will be acidic. The pH range of acidic solution is 0 to 6.9.

The solution having pH equal to 7 is termed as neutral solution.

Thus the given statement is False.
