    On a practical sheet, it says temperature rise at neutralisation.
    Do I write down that temperature or the temperature difference.

    e.g. 28.8 or (28.8-20) = 8.8

    Temperature difference.
    you see that's what I thought.
    Damn edexcel, never make things clear.

    It says on the sheet.
    At the point of intersection read off the max temp and the volume of sodium hydroxide added and the temperature rise at neutralisation on your results sheet.

    Draw tangents at the points of the Maximum curve you get.

    Where they intersect is the nuetralization, then minus it from the total intial temp which can be calculated by use of the volumes and temp of each chemical if they are both not at the same.
