Identifying an Unknown Carbonate

[agalakatos]

Hi everyone,

I have a lab that I will be working on and need assistance.

We are given one out of 9 possible carbonates (Lithium Carbonate, Magnessium Carbonate, Rubidium Carbonate, Calcium Carbonate, Strontium Carbonate, Potassium Carbonate, Zinc Carbonate, Sodium Carbonate and Silver Carbonate). We will be mixing one of the carbonates with HCL to form Water, Carbon Dioxide and an ionic compound.

During the lab, we are to determine the amount of Carbon Dioxide produced, but we need to determine the Carbonate from this piece of info. I was told that we are not able to simply calculate the amount of carbon dioxide produced in each of the possible carbonates, rather we are to figure out the carbonate using algerbra and stoichiometry.

ANY help would be greatly appreciated
