Question

Correct Each row of the table below describes an aqueous solution at . The second column of the table shows the initial components of the solution. Use the checkboxes in the third column to explain the type of the initial solution. The fourth column describes a change in the solution. Use the fifth column to predict how the change in the solution will change its pH.

Answer 1

Based on the given table;

A is a basic solution; addition of HClO₄ makes pH lower.

B is a neutral solution; addition of KI make pH stay same.

C is an basic solution; addition of NaClO₄ makes pH stay same.

D is a neutral solution; addition of KOH makes pH higher.

What changes occur in the pH of the solutions?

The pH of a solution is a measure of the acidity or alkalinity of the solution.

Solutions of pH less than 7 are acidic solutions whereas solutions of pH greater than 7 are basic solutions. Solutions of pH 7 are neutral solutions.

Addition of acids to an acid solution, will decrease the pH, while addition of a base will increase the pH.

Conversely, addition of a base to an basic solution will increase its pH whereas, addition of an acid will decrease the pH of the solution.

Based on the given table;

A is initially a solution; addition of HClO₄, an acid will make pH lower.

B is a neutral solution, addition of a neutral salt such as KI will make pH stay same.

C is an basic solution. When NaClO₄ is added, pH will be same.

D is neutral. Add KOH, and pH will be higher.

In conclusion, pH of a solution is affected by addition of acids, salts or bases.
