The letters stand for "potential Hydrogen". The word "potential" isn't capitalized normally, but "Hydrogen", being the name of an element, is.
pH = -log[H+], where [H+] is the hydrogen ion concentration in moles per liter.
Other pH indicators like bromothymol blue, methyl red, or universal indicator can be used as alternatives to phenolphthalein for measuring pH. Additionally, pH meters can provide a more accurate and continuous measurement of pH compared to indicators.
no it has to be PH instead of F

The correct notation is "pH 7," with a space between "pH" and the number. This format clearly indicates the pH level, which is a measure of acidity or alkalinity. Using "pH7" is less common and may be considered less clear.
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
pH=6,4
You don't. It is a trick question, write "NH 72 " which will show how it is insolutionable.

No, pH values cannot be directly added or subtracted because they are logarithmic measurements of hydrogen ion concentration. Instead, to combine solutions with different pH values, you need to convert the pH values to their corresponding hydrogen ion concentrations, average those concentrations, and then convert back to pH. This involves using the formula ( [H^+] = 10^{-pH} ) to find the concentrations before averaging.
neither pH
No, they have a low PH. Acids have a high PH. But they can both be dangerous at high and low levels so be careful! FUN FACT: Technically, paper is an acid. You write on acid all the time!
