What is the pH value of a neutral aqueous solution at standard ambient temperature and pressure?

💡 Solution & Explanation

The pH scale ranges from zero to fourteen, where a pH of exactly seven indicates neutrality, representing equal concentrations of hydronium and hydroxide ions in pure water. Values below seven signify acidic conditions, while values above seven indicate basic or alkaline conditions. The pH scale was introduced by the Danish chemist Søren Peder Lauritz Sørensen.
