Answer: The correct answer is A) Basic.
pH is a logarithmic scale that is used to measure the acidity or basicity of an aqueous solution. Its value ranges from 0 to 14. pH 7 indicates that the solution is neutral (like pure water), value above 7 indicates that solution is basic whereas below 7 indicates that the solution is acidic.
Therefore, a solution with higher pH levels is more basic.
Example- pH of baking soda ( NaHCO₃) is 9.
