Hi,
the following includes my calculations of how to prepare a hydrochloric acid solution that will only dissolve 10% of a gram of calcium carbonate. Please take a look and tell me if I got it right and if not, tell we were did I went wrong. Thanks in advance!
--------------------------------------…
Number of moles in grams = mass (grams) / molar mass
Number of moles in 0,001 grams CaCO3 = 0.001 / 100 = 0.00001 mole
This will react with double the moles of HCl = 0.00001 x 2 = 0.00002 mole
Converting moles to grams of HCl needed:
HCl gram= molar mass x moles = 36.5 x 0.00002 = 0.00073 gram
0.00073 grams of HCl will react with 0,001 gram CaCO3
0.00073x1179 {density of HCl (22 Baume) in grams}=0.86 milliliter ~ 0.1 milliliter
0.1 milliliter of HCl will react with 0,001 gram CaCO3
0.01 milliliter of HCl will react with 0.0001 gram CaCO3 --------- the 10% per 1 mg
If all the previous calculations considered a 1N HCl solution
Dilution:
Concentration 1 x volume 1 = concentration two x volume 2
