Another one ✨Fave — let's solve it. The question asks about the color of phenolphthalein when added to "any mono..." (likely referring to an acidic solution, such as a monobasic acid). Step 1: Identify the indicator. The indicator mentioned is phenolphthalein. Step 2: Recall the color changes of phenolphthalein. Phenolphthalein is an acid-base indicator that changes color based on the pH of the solution: In acidic solutions (pH below 8.2), phenolphthalein is colourless*. In basic (alkaline) solutions (pH above 10), phenolphthalein is pink or magenta*. Step 3: Determine the color in an acidic solution. If phenolphthalein is added to an acid (like a monobasic acid), the solution will be acidic. In an acidic solution, phenolphthalein remains colourless. The final answer is B What's next?
