Water has a pH equivalent to which type of solution?

Explanation:
pH measures how acidic or basic a solution is. Pure water at room temperature autoionizes into equal amounts of hydrogen ions and hydroxide ions, so [H+] = [OH−] = 1×10⁻⁷ M. The pH is the negative log of the hydrogen ion concentration, giving pH = 7. This defines a neutral solution. An acidic solution has pH < 7, and a basic (alkaline) solution has pH > 7, so water is neutral. (Note: at temperatures other than room temperature, the neutral pH of water can shift slightly, but under standard conditions it is 7.)
