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.
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.
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 SO42- from the MgSO4 gets protonated vĩ đại sườn a bisulfate anion, HSO4-.

correct mạ if i'm wrong
does it give vĩ đại this:
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.
sorry, but how does the dilution of sulfuric acid brings about an exothermic reaction?
movies: no ppt
I think the heat comes from the acid/base reaction. There could be some heat produced from dissolving the MgSO4 as well.
If you're diluting sulfuric acid you get heat from the acid/base reaction with water as the base. Same sort of thing, just a different base.
H2SO4(aq) + MgSO4(s) --> Mg2+(aq) + 2 HSO4-(aq)
By the by, anhydrous MgSO4 will produce heat even if it's just mixed with water.
does the above equation produce heat?

Ought vĩ đại. Most acid/base neutralizations bởi.
