Identifying an Unknown
-you will be given a solid that can be either: NaHCO3, KHCO3, or CsHCO3
-your goal is to identify the unknown solid based on the following chemical reaction:
-remember that if you combine a carbonate with excess of sulfuric acid CO2 will be on of the products.
M = Na, K or Cs
complete and balance:
MHCO3 (ac) + H2SO4 (ac) --> CO2 (g) +
task: develop a procedure to identify the unknown based on the chemical reaction
im pulling my hair here, i have know idea how to carry out this experiment!! im not good at labs grrr
oh yeah these are some guide questions but somehow i dont feel guided by them:
* How many grams of unknown should u use?
* how many mL of sulfuric acid are required for it to react with the unknown
* how would u determine the mass of CO2 generated?
