    for the total volume of acid in C3, last question did anyone put 35 or is that just me (5cm3 of hydrochhloric acid plus 30 more???)
    I put 55 because it was 30 for the maximum temperature and then there was already 25 of alkali in the flask. I don't know if that is right though...

    I didn't put either I just said what it does
    I said its a smart metal so might miss a mark there but then i described how it reverts to original size with temp etc so probs 2/3 unless smart metal is accepted...

    There is 25cm3 initially, and 30cm3 of HCl has been added at that point, so there is 55cm3 overall.

    Yeah it was 55 i think. They were adding 5cm continuously so they added 30cm in total + the 25 = 55.
