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

  • chemistry -

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