    oxalic acid and most other carboxylic acids are weak, and sodium hydroxide is a strong alkali, so its weak acid strong base

    Apart from amonium being soluble y else is it useful for fertilisers
    The answer was because it contains nitrogen which is used for plant growth. Not sure if answer is right tho

    Its ok someone said the answer before i did not see but the one about Potassium Carbonate being made with water and the water being cloudy becasue ions were present so it asked which ions.

    My other question though would be for that question drawing the equipment for the flowers that you were getting essential oils from what did you all draw?

    I basically just drew what the question said, so a water bath with a test tube in it
