    What is a titration calculation ? Would I be able to learn it now ?
    Try looking it up on bbc bitesize or on youtube. They aren't really that hard so you should be able to learn it.

    Yes, they are very easy. The formula is in the data book
    Is that the n1 c1 stuff ? What do they even mean ?

    They'll give you a diagram showing a pippete. They'll then give you the concentration and volume of one of the acids and one of the alkalis. They'll then ask you to find the missing concentration or volume of the acid or alkali. It's usually the last question

    Do we need to learn about corrosion and the rusting of iron for the exam. Our teacher only skimmed over it since he was confident its not going to be in the exam. Given the SQA's recent pattern of putting everything that wasn't in previous papers for subjects in the 2016 ones im starting to worry that they might decide to.

    We shouldn't need to. It's not in the course notes.

    just written it out - now downloading the app to send a picture of it.

    I think we should all do the same open-ended question, and get our own answers, and once we have all agreed on a suitable answer we will move on to the next one...

    Here's the first open-ended question...

    Metal + Acid = Salt + Hydrogen
    Metal Oxide + Acid = Salt + Water
    Metal Carbonate + Acid = Salt + Water + Carbon Dioxide
    Metal Hydroxide + Acid = Salt + Water
    What's the significance of remembering these?

    They'll give you one of those questions and then ask you what type of reaction it is, or the products of those reactions

    Add to water to see if it is soluble
    Heat up to see if the melting/boiling point compares to an ionic/ covalent.
    Flame test to see if a colour is given off.
    Burn to see and capture the gas given off - CO2 = milky, o2 = relight a glowing splint
    add to water and test for pH - ionic - pH7, covalent - <pH7

    I usually identify it by the alkali and the acid and the salt or whatever. It's usually clear,

    Good answer, if that came up I'd be happy because it's literally open-ended and not bloody stupid like some of them.

    Just write the equation and see what the end products are - I find it easier than remembering.
