5. A-level Textbook

This text book is an ongoing project. At the moment it as an amalgamation of all the written material I have. It is not therefore syllabus specific. Some material may be the same as what is on the revision guides but some has more extensive explanations. Over time I will add to the explanations to turn the revision guide bits into something more detailed. I will also add to the questions that appear in some chapters.

    Loads of hard work has gone into producing these notes – hope students appreciate the hard work of dedicated teachers – an inspiration to Chemistry students 🙂

    For ‘questions on errors’ in titrations, for part (d) surely there should be no effect on the calculated value of [NaOH] as the water doesn’t affect the number of moles of either reagent used and the moles of potassium hydrogenphthalate measured out by the pipette is the same?

    Great resources! However it would be superb if you have more questions for each topic and give answers to the questions.:)

    Hey, thank you so much for notes. I was just wondering do you know where i can obtain the answers from as i am working through the questions from Unit 1, Module 1. Thanks again for your help.

  7. Lynne

    It would be great if you could supply the answers to the mole questions in 1.21 and 1.24 (the new guides). Ive done them but not sure if I got them right and I would love to know. Thanks for your notes. Love them.

        Got the answers – this will really help me – just in time for my amount of substance test on monday. thank you so much.

        I have looked at the answers but for some i am getting different answers to you, for example for 1.24 calculations and chemical reactions, question 1.1 your answer was 4.21g but i am getting 6.80g can you please explain how you are getting this?

      3. chemrevise Post author

        I would prefer you to show me how you get 6.80. Check you are using the atomic mass of Titanium (Ti). I suspect you might be doing it with thallium (Tl)
