    Need a bit of help in working through this. Here's the instructions :

    Plan 2 ways to determine the conc of a solution of sulphuric acid. One method has to be measuring volume of gas.

    Use following chemicals in experiment :
    Aqueous sulphuric acid (approx 10 mol-3)
    Solid magnesium carbonate
    Aqueous sodium hydroxide (conc 0.1mol-3)
    Indicator of your choice
    Diastilled or deionised water.

    I'm pretty poor at chemistry so any help is very much appreciated.
    Important questions that bother me are :

    I know that the other method is titration but what suitable indicator to use and the colour change?

    For collecting the gas you use a syringe right then take the amount of gas lost when the reaction has finished but then how do you work out the conc of sulphuric acid?

    What can I say about the deionised water for chemical knowledge?

    Any other information is a extra bonus for me

    Oh 1 more thing how much magnesium carbonate is a suitable amount? I know it has to be in excess but still unclear as to by how much.

    I'm doing this at the moment
    Indicator to use would be phenolphthalein I'm pretty sure as it is strong base and acid. Colourless to pink is colour change I think corect me if I'm wrong as I've still to get that far on my mine.
    Maybe I'll answer the others later. Hope that helps a bit.
