Answer: When water is added to vinegar, the vinegar's acidity decreases, which results in a higher number on the pH scale. However, diluting vinegar with water can never make it alkaline, because water itself is not alkaline; the pH of the mixture can't be higher than the higher pH value of the two components.
Explanation: it loses acidity. Diluting it can never make it alkaline and the PH mixture can’t be higher.
