A scale developed to measure the concentration of hydrogen ion in a solution is known as pH scale where p in pH implies ‘potenz’ in German.
pH scale ranges from 0 (highly acidic) – 14 (highly alkaline).
The pH of a neutral solution is 7.
Acidic solution is represented by a value less than 7 on the pH scale.
Whereas basic solution is represented by a value greater than 7 on the pH scale.
An increase in OH^–ions concentration in the solution results in increase in the strength of alkali hence the value of pH increases.
Acids giving rise to more H⁺ ions are strong acids whereas those giving rise to less H+ ions are termed as weak acids.
Similarly bases giving rise to more OH^- ions are strong bases whereas those giving rise to less OH- ions are termed as weak bases.
Salts of a strong acid and a strong base are neutral with pH value of 7.
Salts of strong acid and weak base are acidic with pH value less than 7.
Salts of a strong base and weak acid are basic in nature, with pH value more than 7.
