if a solution has a greater concentration of hydrogen ions than hydroxide ions, then it is....\nacidic\nbasic…

Brief Explanations:

In chemistry, a solution with a higher concentration of hydrogen ions ($H^+$) than hydroxide ions ($OH^-$) is defined as acidic. A basic solution has more $OH^-$ ions than $H^+$ ions, and a neutral solution has equal concentrations of $H^+$ and $OH^-$ ions.

Answer:

acidic
