Question

Calculate the pH and the pOH of an aqueous solution that is 0.050 M in HCl(aq) and 0.060 M in HBr(aq) at 25℃.

Answer 1

Concepts and reason

Solutions are classified into acid or base based on the pH value. If pH value is less than 7, the solution is acidic and if pH is greater than 7, the solution is basic. pH of a solution can be determined by identifying the concentration of in the solution.

Fundamentals

…… (1)

pH is the measure of hydrogen ion present in a solution. It is the negative logarithm of the H⁺ concentration to the base 10. It gives the acidic strength of the solution.

…… (2)

pOH is the measure of the hydroxide ion present in a solution.

It is the negative logarithm of the concentration to the base 10. It gives the basic strength of the solution.

Ionic product for water:

…… (3)

…… (4)

Ans:

The pH and pOH of the aqueous solution is
