Question

how strong are acid or base solutions

Answer 1

The range from 0 to 14 gives a measurement of comparative strength of acid and base solutions. Pure water and other neutral solutions have a pH value of 7. A pH value less than 7 indicates that the solution is acidic, and a pH value greater than 7 indicates that the solution is basic.

Answer 2

acid
if the acid has 1 as it's pH value then it is an strong acid
if the acid has 6 as it's pH value then it is a weak acid
base
if the base has 14 as it's pH value then it is a strong base
if the base has 8 as it's pH value then it is a weak base
