WebIn pure water at room temperature the K w value tells you that: [H +] [OH -] = 1.00 x 10 -14 But in pure water, the hydrogen ion (hydroxonium ion) concentration must be equal to the hydroxide ion concentration. For every hydrogen ion formed, there is a … WebThe pH of pure water is 7, the negative logarithm of 1 X 10-7. A neutral solution is one that is neither acidic nor basic. The hydrogen ion concentration equals the hydroxide ion concentration, and both equal 1 X 10-7M. In a neutral solution, then, pH = pOH = 7.
