    Hi,

    I am having difficulty understanding this question:

    compound A is insoluble in water but soluble in alkaline solution, where compound A is a carboxylic acid.

    explain why A is soluble in a alkaline solution (and not in water)

    Why would a carboxylic acid not be soluble in water!? and what properties makes its soluble in the alkaline?

    Thank you

    It is only a weak acid, so is not fully dissociated in water, and evidently has a large hydrocarbon portion which prevents it from being soluble in water.

    Add base to your water and it is fully dissociated and now soluble.
