Question

in a neutral solution the concentration of ______. hydrogen ions is greater than the concentration of hydroxide ions hydrogen ions is less than the concentration of hydroxide ions hydrogen ions is equal to the concentration of hydroxide ions water molecules is less than the concentration of hydrogen ions water molecules is less than the concentration of hydroxide ions

Explanation:

A neutral solution has a pH of 7. At this pH, the concentration of hydrogen ions ($H^+$) and hydroxide ions ($OH^-$) is equal, based on the self - ionization of water equilibrium ($H_2O
ightleftharpoons H^++OH^-$) and the definition of neutrality in aqueous solutions.

Answer:

C. hydrogen ions is equal to the concentration of hydroxide ions
