here is a website to help understand about ph.http://antoine.frostburg.edu/chem/senese/101/acidbase/faq/what-is-pH.shtml
the ph of water is 7. some compounds dont change ph because they dont cause any change in H cation nor OH anion. if you put NaCl in water the ph is still 7.
ph = -1logH. H is the molarity of the H cation in solution.
