What is pH in brief?? |
|
Answer» \tA 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.\tpH scale ranges from 0 (highly acidic) – 14 (highly alkaline).\tThe pH of a neutral solution is 7.\tAcidic solution is represented by a value less than 7 on the pH scale.\tWhereas basic solution is represented by a value greater than 7 on the pH scale.\tAn increase in OH– ions concentration in the solution results in increase in the strength of alkali hence the value of pH increases.\tAcids giving rise to more H+ ions are strong acids whereas those giving rise to less H+ ions are termed as weak acids.\tSimilarly bases giving rise to more OH- ions are strong bases whereas those giving rise to less OH- ions are termed as weak bases.\tSalts of a strong acid and a strong base are neutral with pH value of 7.\tSalts of strong acid and weak base are acidic with pH value less than 7.\tSalts of a strong base and weak acid are basic in nature, with pH value more than 7.
