Write the equilibrium constant for the dissociation of water. Rewrite it in terms of the ionization of water constant Kw. The concentration of hydronium and hydroxide equals what value?
Homework Answers
During the dissociation of water molecule, one molecule of water gets protonate and the other gets deprotonate. This is also called as the auto-ionisation or autodissociation of water. The equilibrium reaction is as follows and the value of hydronium and hydroxide ion is shown in the image below:
