the experiment was reacting Mg with H2SO4 and measuring vol. of gas to determine the Ar of magnesium. i am stuck on the extension opportunities.
1. when you add the Mg you are introducing two errors: one results in smaller volume of gas and the other a larger volume of gas. what are the errors and what effect do they have on the calculated Ar of Mg? - i can’t think of anything that would lead to a larger volume of gas
3. plan a modification to this experiment so Mg can be mixed with acid with no/minimal error in measured vol. of gas - what can i change? i can only think of putting the bung in quicker 😣
5. alternative method to determine Ar of Mg is purification of the MgSO4 synthesised. what hazards would be involved in this purification?
any help is appreciated thank you
