Question

A substance with equal numbers of H+ ions and OH- ions is a basic solution. True False

Answer 1

A substance with equal numbers of H+ ions and OH- ions is a basic solution. This is False. It will be neutral.

Answer 2

Answer: False

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

$pH=-\log [H^+]$

$pOH=-\log[OH^-]$

When the concentration of $[H^+]=[OH^-]$, the solution is neutral, $H^+$> $OH^-$ , the solution is acidic and if $H^+$< $OH^-$ , the solution is basic.
