Question

A solution has a pH of 8. Which best describes the solution? a strong acid. a strong base. a weak acid. a weak base.

Answer 1

The correct answer would be a weak base.

Answer 2

Answer:

A Weak Base

Explanation:

As we know that the concentration of H ions in the solution will decide the property of the solution.

As we know that pH is defined as

$pH = -Log[H^+]$

so now if we found that value of pH lies less than 7 then it is an acid and the strength of the acidity will increase as we go down with its value.

Also if the value of pH increases more than 7 then the solution becomes basic and the nature will increase more basic as we move more on the value of 7.

Since the pH here is given as 8 so this is a basic solution and also it is not very high or strong basic as its value is still close to 7

so correct answer is

a weak basic
