Question

In a neutral solution the concentration of _____.

hydrogen ions is less than the concentration of hydroxide ions
water molecules is less than the concentration of hydrogen ions
hydrogen ions is equal to the concentration of hydroxide ions
water molecules is less than the concentration of hydroxide ions
hydrogen ions is greater than the concentration of hydroxide ions

Answer 1

In a neutral solution, the concentration of **hydrogen ions is equal to the concentration of hydroxide ions**. This is the defining characteristic of a neutral solution, typically exemplified by pure water at 25°C, where both concentrations are \(1 \times 10^{-7}\) moles per liter.
