wait hold on, for the graph shoudnt it be a curve?
@DrMonaSeif Жыл бұрын
Yes it is a curve, but because they are pretty much straight lines rather than curves in this question as the points align in an almost straight line; thus you should end up with something like that, just make sure you draw them freehand and not with a ruler, mine got modified by the app.

Hi, I am a bit confused on Question 2d. I don't understand why is there no change. Also, for question 3e, how would I know whether the anion is sulfate or sulfite as it shows both a positive test for sulfate and sulfite. Could you please help me out? Thank you!

why was there no change in question 2 (h), is it because 50 degrees celsius has higher solubility?
@DrMonaSeif Жыл бұрын
Yes the solubility at 50 is higher than that at 80, so when the solution is cooled NO precipitate will be formed and the solution will remain colorless.

i always get confused when they ask for a curve and when they dont
@DrMonaSeif Жыл бұрын
There is nothing to get confused over, Cambridge is usually pretty straight forward, when they ask for a curve you draw them a curve and when they ask for a straight line that is what you draw, as simple as that👍.
