-pH stands for potenz Hydrogen, pH value indicates whether the substance is acidic, basic of neutral. - pH less than 7 is acidic -pH greater than 7 is basic - pH equal to 7 is neutral ( neither acidic nor basic)
pH value are the value used to determine wheather a solution is acid or basic in nature Acids= pH<7 Bases= pH>7 Neutral= pH=7
pH scale is a numerical representation of acidity and basicity of the substances. It varies from 1 to 14. The solutions with a pH value less than 7 are referred to as bases and those with a pH value of 7 are to as neutral.
pH is the negative logarithm of H+ ions. A substance having <7 pH is a Base A substance having >7 pH is an Acid Exact pH 7 is a neutral substance
