@MaChemGuy also can I ask for a pH curve, if youre asked to calculate moles of the acid (where base is being added to acid), is it acceptable to just read off the starting pH and use the weak acid formula to work out concentration?
@MaChemGuy

@@stareyedstudygirl I’d need to see the question but it sounds correct. Did they give the volume the weak acid was in?

@MaChemGuy sorry ignore me, I said moles but the Q asked for concentration, everyone online seems to have used the half equivalence? I was just a bit lazy and thought this would be a quicker way

So for industry, if you have an equation with solids and gases involved and are asked to comment on the effect of an increase in pressure, do you ignore how many moles of solid you have completely?

@sameerishaque7635

You need to focus on both. Past papers are just so you can understand the type of questions and how to respond i.e method of working out. Content always comes up in multiple choice questions. Like you might get a question asking if Mg or Na has a high first ionisation energy. Practice questions and look at the content that will come up

it doesnt matter for a diagram but if its that wierd diagram (sorry i dont know what its called) then its most neg element | most neg ion || positive potential ion | most postive element for example Zn | Zn 2+ || Cu 2+ | Cu where Zn electrode is most negative so its effectivly flipped from the eq you are given in the question hopefully you understand and good luck!
