At 10°C, the pH of a 1 mol L–1 solution of a substance X is 7.10. would X be a base or an acid or neither?
i think its base
right. A pH of 7.0 is neutral. >7 is base; <7 is acid
To determine whether substance X is an acid, a base, or neither, we need to analyze its behavior with respect to pH.
pH is a measure of the concentration of hydrogen ions (H+) in a solution. A pH value less than 7 indicates an acidic solution, a pH value greater than 7 indicates a basic (alkaline) solution, and a pH of 7 indicates a neutral solution.
In this case, we are given that at a temperature of 10°C, the pH of a 1 mol L–1 solution of substance X is measured to be 7.10. Since the pH of 7.10 is slightly above 7, we can say that substance X is slightly basic.
To summarize, substance X is a weak base since the pH is above 7, indicating a slightly alkaline solution.
