    Q : write products formed when polyester is heated with aqueous sodium hydroxide

    I know is hydrolysis , and the product will be alcohol and carboxylic acid ... but will the -OH in carboxylic acid replaces with -ONa or not ??
    It say heated with , but doesn't mean react .. so does heated means react ?

    Heated means heated. However, reactions are faster at elevated temperatures.

    If there is enough base it will neutralize the acid.

    thank you ..

    so what you mean is that to determine whether is -OH or -ONa , we have to know the amount of sodium hydroxide ?
