Edexcel GCSE Chemistry Paper 1 Higher Tier 1CH0 1H - 27 May 2022 [Exam Chat]

so whos ready for tomorrow

i need to go over everything after sc11 (electrolysis all the way to fertilisers and fuel cells and what not)
so deffo not me

How did everyone find it

Found it pretty difficult but it was what I expected, no easier and no harder. What did everyone get for the gradient question, it was 5 marks and idk why

Which question was that?

I actually loved this paper. I managed to have around 25 minutes spare haha. Because I liked the paper i fear grade boundaries are gonna be high

Yep the test was super easy, what did you write for the one where it asked you to explain why metal Y didn't react is it because metal sulfates are insoluble?

Guys can everyone put some answers that they got for the questions in the chat ?

I wasn't thinking for the last question on gas calculations so I've lost at least 4 marks 😭😭 because of time. Other than that, it was reasonably accessible

Chemical cell - brightness decreases over time as the zinc and copper is being used up and once the zinc and copper have been fully used, the bulb won't radiate any light

Metals in order of reactivity - XWYZ

Obtain ammonium sulfate - heat the solution in an evaporating basin, stop heating when some water is left and crystals start to form, pat crystals dry and leave in a warm place for cooling down

why potassium chloride (?) has a high MP - strong electrostatic forces of attraction between ions, takes a lot of energy to overcome these forces

how to get accurate titre - use white tile to see colour change better, read from bottom of meniscus (not sure about the meniscus one as it did say that the volumes were read accurately)

for 2 answers where we had to work out percentages, one i got 28.6 and the other was 51 to 2sf
these are the ones i can of think rn

edited for grammar

Yeh i put that too. Usually in mark schemes it says reactants used up and so voltage across the bulb or cell decreases, meaning less light.
