1.	(a) The pH of a cold drink is 5. What will be its action on blue and red litmus solutions ?(b) The pH values of three acids A, B and C having equal molar concentrations are 5.0,2.8 and 3.5 respectively. Arrange these acids in order of the increasing acid strengths.
Answer» (a) The cold drink turns blue litmus red because of its acidic nature. It will have no action on red litmus. (b) A < C < B.B will have maximum acid strength because pH is inversely proportional to concentration of hydrogen ions in a solution.
