Question

Two solution A and B were found to have pH value of 6 and 8 respectively. The inference which can be drawn is that

• A. the acid strength of the solution B is higher than that of A.
• B. A is an acid while B is a base
• C. both are acidic solutions
• D. both are basic solutions.

Answer 1

The correct option is B

A is an acid while B is a base

The explanation for the correct option (B):

• pH refers to the potential of Hydrogen (H).
• pH is a scale that is used to determine the acidity as well as basicity of a solution. It ranges from 0 to14.
• The pH value less than 7 indicates that the solution is acidic in nature. The pH value greater than 7 indicates that the solution is basic in nature and the pH value of 7 indicates that the solution is neutral.
• The value of pH for solution A is 6. This shows that solution A is acidic in nature and A is an acid.
• The value of pH for solution B is 8. This shows that solution B is basic in nature and B is a base.

Final Answer: Hence, option (B) is correct. A is an acid while B is a base.
