    Hi guys, quick question.

    To get an A* in OCR Chemistry A, does one have to achieve at least 90% UMS in each A2 module (84/90, 135/150, 54/60) or is it just 90% UMS overall at A2 (270/300, so one module's scores can make up for another)? This is of course, provided As are achieved across all 6 modules.

    In your F324 guide, the very last page you have the page of A2 Reactions ;

    You've listed the products for the alkaline hydrolysis of esters as the carboxylic acid + salt, but in the textbook it says it's the salt of carboxylic acid + alcohol. Which is correct?

    The carboxylate salt and alcohol is correct.

    Good spot! Of course the carboxylic acid present will be neutralized by the alkali
