In an experiment, samples of two colourless solutions X and Y were taken. On adding turmeric solution, X acquired yellow colour and Y became brick red. What can you conclude about the nature of X and Y ?
Y is a base and X can not be known with above information
Turmeric (haldi) is a natural acid-base indicator: it remains yellow in neutral and acidic solutions, but turns brick red (reddish-brown) in the presence of a base.
Since solution Y turns the turmeric brick red, Y must be a base.
Solution X keeps the turmeric yellow, but turmeric stays yellow for both acidic and neutral solutions — it does not turn a distinct colour for acids the way it does for bases. So X could be either acidic or neutral, and its exact nature cannot be determined from this test alone.
Hence, the correct conclusion is that Y is a base, while the nature of X cannot be determined from the given information.
