What is the actual hydrate formula for Barium Chloride? I did a lab and got 5.4 but i was told to find the actual formula online.
Same for MgSO4.. i got 7.74 but i need to find the actualy hydrate formula aswell

DrBob222,
I believe it's BaCl2*2H2O (the dihydrate).
For MgSO4, I believe it's MgSO4*7H2O, (epsom salt) but various other hydrates are known.
