The p stands for "power". The H stands for hydrogen, as is common in chemistry; in this case, it specifically means the hydrogen ion H+, which in water actually exists as H.x(H2O)+, where x is generally 1 to 3 or so.
You will occasionally see the "p" notation in other things, and it generally means "the negative log to the base 10 of" whatever follows it. For example, pKa means the negative log to the base 10 of the acid dissociation constant.

What pH is pure water?
Pure water has a pH of 7, which is considered neutral on the pH scale.
Does acids has a higher pH than water?

Does water have a measurable pH value?
yes, pH can be measured in a water (an aqueous) solution.
Does boiling water affect its pH?
Adding water will affect the pH. Adding water will shift the pH towards the neutral mark. In the case of an alkaline solution, there will be a decrease in pH.
PH of salts insoluble in water?
Salts that are insoluble in water typically do not affect the pH of the solution. This is because they do not dissociate into ions in water to contribute to the H+ or OH- ions that determine pH. If there are impurities or other substances present that can dissolve and affect pH, then the pH may change.
How does the circulation water in a stand-water ecosystem affect the ecosystem?
Circulating water in a standing water ecosystem can affect the ecosystem. This is because it can change the PH of the water killing the existing organisms.
