How does pH affect net charge?

Net charge always is zero. Changing the pH cannot cause a solution to be electrically charged.


I am assuming that you are referring to a solution.

Some species ionize well at certain pH. For example, weak acids such as ethanoic acid (#"CH"_3"COOH"#) dissociate at high pH.

However, the net charge does not change as for every positive charge formed during dissociation, 1 equivalent of negative charge is formed as well. Therefore net charge remains at zero.
