When water dissociates, what is released: more H+ or more OH-? Explain Please

Jan 18th, 2016

Thank you for the opportunity to help you with your question!

When water dissociates, one of the hydrogen nuclei leaves its electron behind with the oxygen atom to become a hydrogen ion, while the oxygen and other hydrogen atoms become a hydroxide ion.

Since the hydrogen ion has no electron to neutralize the positive charge on its proton, it has a full unit of positive charge and is symbolized as H+.

The hydroxide ion retains the electron left behind and thus has a full unit of negative charge, symbolized by OH-.  The hydrogen ion (proton) does not wander long by itself before it attaches to the oxygen atom of a second un-ionized water molecule to form a hydronium ion (H3O +)

Therefore, we can conclude and say that water releases both H+ and OH- in equal ratios. This explains why water has a PH of 7

Please let me know if you need any clarification. I'm always happy to answer your questions.
