Chemistry AS Planning ExerciseWatch
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
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.
