Homework Help: Is magnesium hydrogencarbonate commonly found in lab?

  1. Jul 5, 2012 #1
    1. The problem statement, all variables and given/known data
    Hi,there is a question from my textbook:
    Name FOUR substances commonly found in the laboratory to prepare magnesium sulphate by reacting with dilute sulphuric acid.


    2. Relevant equations



    3. The attempt at a solution
    Here is my answer:
    Mg(OH)2,MgO,MgCO3,Mg(HCO3)2
    Here is the model answer:
    Mg,Mg(OH)2,MgO,MgCO3

    Mg(HCO3)2 react with H2SO4 to give MgSO4:
    Mg(HCO3)2 (aq) + H2SO4 (aq) --> MgSO4 (aq) + CO2(g) + H2O(l)

    Is it possible for me to write Mg(HCO3)2?If not,please explain briefly.
    THX a lot.

    Hi :smile:

    Our lab has it, and I don't think its uncommon at all.

    Can you show me a bottle of your magnesium bicarbonate? I was under the impression it was fairly unstable.

    Apparenbtly it is stable enough to be offered for sale, google for its CAS number 2090-64-4.
