Well my gradient is almost the same as yours (~0.7). And I did exactly what you said! Thanks for helping.
I did the calculation using your gradient and the x value was 0.31, so how is that 'rounded' to 0.50?
Because I did that with my value and the x-value again was 0.31, so I thought it was wrong.
leebux101:
when i did it with my value, i got x as 0.46,
i would suggest change ur line a bit, make it more fitting
the points i used for my gradient are
x axis >> 7.5 to 0
y axis > 5.2 to 0
try again and tell me then.. =D

As long as its a problem of accuracy, then thats a relief, I thought I was doing it all wrong. I will repeat the graph and hopefully I'll get the value right.
THanx for the help.

I have another question, in may june 2010, q1 (c), the drawing. What do we draw so that "over-heating of the solution is prevented" ?
A water bath?

hey!
I was wondering if there is anything specific we need to know for p5 prep apart from practicing the past papers that is!
