MgSO4 + H2SO4 what does it yield?

Bạn đang xem: mgso4+h2so4

haf tried vĩ đại tìm kiếm the net for this equation but vĩ đại no avail. did the experiment. got an exothermic one.

thanks

it was probably just the Mg and SO4 bond being broken. the two cannot react.

well, here is the instruction of the experiment

Place a pea-sized amount of Epsom salts , MgSO4 in a small, clean test tube that has been rinsed with distilled water.

Add 1-2 drops of 18M sulfuric acid.Descibe your observations.

18M H2SO4 would break the bonds reeeeal easily. that's what it is.

ssssss

Well if it would have been any halogen then the a displacemoent reaction could have been occured But since SO₄ is attached with Mg it could not be replaced by another SO₄ of Sulphuric acid.

It's probably just an acid/base reaction. The SO₄^2- from the MgSO₄ gets protonated vĩ đại sườn a bisulfate anion, HSO₄^-.

correct mạ if i'm wrong

does it give vĩ đại this:

Mg(HSO4)2

magnesium(II) bisulphate?

oh, btw. my observations:

exothermic, no change in color. i cant confirm whether there are bubbles or not.forgot abt it

There's a fair amount of water in H₂SO₄, so sánh I would think that it would stay in solution. Did you observe any precipitates?

If you use a concentrated sulfuric acid then magnesium hydrogen sulfate can be formed, but unfortunately, it can be more soluble in water phàn nàn the magnesium sulfate itself.
So nothing is observed, except some heat due vĩ đại dilution of sulfuric acid.
