What happens to the pH of water as the temperature is raised ?
This is good question, and can be answered by reflecting on the bond-breaking nature of the acid-base reaction.
We write the autoprotolysis of water as:
Another way to look at it is to consider that it is a bond-breaking reaction that requires energy to break a strong
The dissociation of water is given by:
This means that as the temperature increases Le Chatelier's Principle predicts that more water will dissociate as the position of equilibrium shifts to the right.
This means the concentration of
This does not mean that the water has become more acidic since
