Detailed explanation-1: -The abbreviation pH stands for potential hydrogen, and it tells us how much hydrogen is in liquids-and how active the hydrogen ion is.
Detailed explanation-2: -In 1909, a chemist called Sørensen devised a system of measuring the amount of free H+ ions in a solution. He called it the pH scale because, in German, potenz Hydrogen means “Hydrogen concentration”.
Detailed explanation-3: -pH is a figure that represents potential hydrogen, and is the measure of acidity or alkalinity in any water-soluble substance. pH values are represented on a logarithmic scale with numbers 1-14 with 7 being a neutral point.
Detailed explanation-4: -The full form of pH is “potenz hydrogen” i.e. power of hydrogen.
Detailed explanation-5: -pH is a numerical way of defining the hydrogen ion concentration of a liquid. It is actually the negative logarithm (to the base 10) of the hydrogen ion concentration. Pure water is neutral.
