Question

As ph increases what happens to the hydrogen-ion concentration

Answer 1

as the Ph increases, the hydrogen ion concentration decreases. it is an inverse relationship.

pH scale based on the Hydrogen ion concentration. the hydrogen ions there are, the more acidic the solution is, which means that pH get closer to zero. when pH pass 7 and get closer to 14, it is basic. 

Answer 2

Explanation:

It is known that pH = -$log [H^{+}]$ or pH = log $\frac{1}{[H^{+}]}$

where      $[H^{+}]$ = 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.
