Question

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

Answer 1

Answer: False

Step-by-step 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.

Answer 2

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