    Sorry another quick que

    When you are hydrolysing ester using sodium hydroxide, does the carboxylate salt exist as -COONa or -COO- Na+ (i suspect the latter but need confirmation). Also, would the former be strictly incorrect?

    I ask because in the AQA textbook they draw them as COONa but in the past paper mark scheme it states "allow -COONa but not covalently bonded Na" (<-- which doesn't even make sense does it COONa is covalently bonded isn't it?)

    Cheers

    Typically you would just write them as -COONa but if you are asked to show displayed formula, it is wiser to show the charged species, as like you said, O-Na bond is not covalent. The way -COONa is written doesn't imply it is covalent, like NaCl which is actually Na+Cl-.
