The pH values ​​of three acidic solutions

The pH values of three acid solutions A, B and C are 1 , 0 and 2 respectively. The order of their acid strength is

Equal volumes of three acid solutions of pH 3, 4 and 5 are mixed in a vessel. What will be the H^(+) ion concentration in the mixture?

(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.

In SHE, the pH of the acid solution
