[SOLVED] magnesium and acid rates reactions

im producing an investigation in the reaction between magnesium a solid metal, and acids of varying concentration, pH and temperatures. these variables are to produce results for comparison. however i am unsure about what apparatus would be most suitable, for this investigation eg heating acids safely, collecting gas products, timing them, volumes to be recorded.

one approach is to record the time taken for a certain amount of H2 gas to be produced in a reaction between Mg and HCl.

what would you suggest? any offers welcome.

I suggest you examine the effect of surface area as well as pH and concentration.

thanks for the suggestions, i have already thought of these as investigations my question is what apparatus should i use to produce results usefull for comparison ie with a good degree of accuracy and minimal possible error.

perhaps someone can suggest such experiments and ideal apparatus?

Have you heard of gas burets? Try this.

ive heard of them, but i don't believe our chemistry budgit at college stretchs that far, I've been looking at measuring gas evolution using an inverted burette and a trough full of water etc but my worry is that I've used it before only to collect oxygen. here i will be collecting hydrogen and I am worried as an amatuer chemist whether i will get accurate readings as i can't think for the life of me wether hydrogen gas will react with the water giving inaccurate results.

You will be fine. Read the article more carefully.
