Question

Write the concentration of the hydrogen ions in pure water.​

Answer 1

Answer:

This expression is an ion product called Kw, which has the value 1.0 X 10-14. In pure water, the hydrogen ion concentration, [H+], equals the hydroxide ion concentration, [OH-]. ... The 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.

➢ In pure water, the hydrogen ion concentration, [H+], equals the hydroxide ion concentration, [OH-]. These concentrations can be calculated from the equation for the ionization of water. The pH of pure water is 7, the negative logarithm of 1 X 10-7. In a neutral solution, then, pH = pOH = 7.
