Step-by-step explanation:
It is known that pH = -
or pH = log
![(1)/([H^(+)])](https://img.qammunity.org/2018/formulas/chemistry/high-school/m2nbvy3rh65enlte122jju408j9ci741mz.png)
where
= concentration of hydrogen ions
Therefore, with the help of this relation we can see that pH is inversely proportional to concentration of hydrogen ions. Hence, when there is increases in pH then there will be decreases in concentration of hydrogen ions or vice versa.
Thus, we can conclude that as pH increases then the hydrogen-ion concentration will decrease.
