Question

limitations of pH scale in detail.​

Answer 1

Answer:

1 to 6 is acidic medium 7 is neutral and more than 7 is basic

Answer 2

Answer:

Limitations of pH Scale

(i) pH values of the solutions do not give us immediate idea of the relative strengths of the solutions. A solution of pH =1 has a hydrogen ion concentration 100 times that of a solution pH = 3 (not three times). A is twice concentrated of a solution, but the values of these solutions are 4.40 and 4.70 (not double).

(ii) pH value zero is obtained in solution of strong acid. If the concentration is , etc. the respective pH values will be negative.

(iii) A solution of an acid having very low concentration, say , can not have pH 8, as shown by pH formula but the actual pH value will be less than 7.
