Im sure you all know which OTC CaCl2 source swim speak of!
Now swim needs to construct a drying tube, and he has never used this chemical before. Can the CaCl2 be used 'as is', or does it need to be dried in oven prior to use?
For more experienced members, do you think anhydrous Cl2 gas can be obtained by initially generating via TCCA/HCl, passing through 2x portions of H2SO4, then finally through a CaCl2 drying tube? Suggestions or answers appreciated
