What Is pH? pH is a measure of a substance’s acidity or alkalinity (also called basicity) – it gives you information about the concentration of hydrogen ions (H+) floating around in something water-based. Low pH means more acidic, high pH means more alkaline. pH values for some common...
Salt, in chemistry, substance produced by the reaction of an acid with a base. A salt consists of the positive ion (cation) of a base and the negative ion (anion) of an acid. The reaction between an acid and a base is called a neutralization reaction. Th
What is the value of [H] for a pH of 6.8? pH of a Solution: The pH of a solution is a measure of the intensity of hydrogen atoms present in a solution. It is simply the power of hydrogen in a solution. pH can be called a scale of acidity in which the value less than 7 corr...
What is pH ?pH is a measure of the acidity of a solution. It is a measure of the concentration of hydrogen ions (H+; proton). The higher the concentration of hydrogen ions in a solution the more acidc it is and the lower their concentration the more alkaline it is. In pure water ...
The pH of a solution is a measure of the hydrogen (or hydronium) ion concentration and is defined as {eq}pH\:=\:-log\:\left[H^+\right] {/eq}. Below pH 7, solutions are considered acidic. Above pH 7, they are considered basic. At pH 7, they...

A pH meter is an electronic device used for measuring the pH which is either the concentration of Hydrogen ions in an aqueous solution or the activity of the Hydrogen ions in an aqueous solution. The pH will indicate if the solution is acidic or basic, but is not a measure of acidity or...
