In an experiment with two colourless solutions M and N, a student adds turmeric solution as a natural indicator. M remains yellow, while N turns brick red. When M is added to N, the brick-red colour gradually fades away. What can be concluded about M and N?

Which indicator turns pink in a basic (alkaline) solution?

A student tests three colorless liquids X, Y, and Z with indicator papers/solutions and records the following observations: • Liquid X: Turns blue litmus red; turns methyl orange red; no color change with phenolphthalein. • Liquid Y: No effect on litmus; stays orange with methyl orange; no color change with phenolphthalein. • Liquid Z: Turns red litmus blue; turns methyl orange yellow; turns phenolphthalein pink. Which option correctly identifies the nature of X, Y, and Z?
