Question

Identify Y and Z in the given Venn diagram.

• A. Y: Window cleaner; Z: Ascorbic acid
• B. Y: Soap; Z: Tartaric acid
• C. Y: Oxalic acid; Z: Milk of magnesia
• D. Y: Milk of magnesia; Z: Oxalic acid

Answer 1

The correct option is D Y: Milk of magnesia; Z: Oxalic acid

• If we split this Venn diagram we will get that Z is found in spinach and it remains colourless in phenolphthalein solution. An acidic solution will remain colourless in phenolphthalein.
• So, we can conclude that Z is an acid and it is found in spinach. Spinach is rich in oxalic acid.
• On the other hand Y is bitter in taste and it turns the china rose indicator to green. China rose indicator turns green in a basic medium.
• So, Y is basic in nature So Y can be soap, window cleaner or milk of magnesia.
• As we already know Z is oxalic acid then Y has to be Milk of magnesia.
