What is the meaning oh pH |
|
Answer» pH scale\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–\xa0ions concentration in the solution results in increase in the strength of alkali hence the value of pH increases.\tAcids giving rise to more H+\xa0ions are strong acids whereas those giving rise to less H+ ions are termed as weak acids pH means potenz hydrogen or power of hydrogen. |
