Question

multiple choice question a base is a substance that ______. lowers h⁺ and increases the ph when it dissociates in water raises h⁺ and increases the ph when it dissociates in water lowers h⁺ and decreases the ph when it dissociates in water raises h⁺ and decreases the ph when it dissociates in water

Explanation:

Bases in water either release $\text{OH}^-$ ions or accept $\text{H}^+$ ions, which reduces the concentration of $\text{[H}^+]$ in the solution. The pH scale is defined as $\text{pH} = -\log_{10}[\text{H}^+]$, so a lower $\text{[H}^+]$ leads to a higher (increased) pH value.

Answer:

A. lowers $\text{[H}^+]$ and increases the pH when it dissociates in water
