    Could someone list all the Physical chemistry practicals?

    These are the only ones I can think of:

    Titration
    Standard solution
    Calirometry (temp change)

    Yeah, they are the required physical chemistry practicals but just as a reminder you also have the required inorganic chemistry practical which involves the tests for anions and cations.

    "Written papers will assess knowledge and understanding of these, and the skills exemplified within each practical"

    1 Make up a volumetric solution and carry out a simple acid–base titration

    2 Measurement of an enthalpy change

    3 Investigation of how the rate of a reaction changes with temperature

    4 Carry out simple test-tube reactions to identify:
    • cations – Group 2, NH4+
    • anions – Group 7 (halide ions), OH, CO32–, SO42–
    5 Distillation of a product from a reaction

    6 Tests for alcohol, aldehyde, alkene and carboxylic acid

    Anyone got any good sources of revision for the required practicals like videos or a website? I don't remember doing the effect of temperature on the rate of reaction

    Can someone please have a look at question 5
    So for Q5.) You have to find out the number of moles of the original solution, by doing n=c x v which is n=12 x 0.01 = 0.12 mol

    You then input this value into the second reaction
    0.12 = 0.250 x v
    Because you want 0.250 moldm-3 solution
    0.48dm^3=v
    so multiply by 1000 to get cm^3
    480 cm^3
    But you started with 10.0cm^3, so 480-10= 470cm^3
    Hope that helps!

    We have NEVER covered NH4+ or OH, CO32–

    Sulphates we covered whilst learning group 2. Can you quickly outline all of them please?!
