A mixture of NaCl, SiO2, and CaCo3 is separated following the procedure given in this experiment. indcate how each of the following procedural changes would affect the maout of the specified substance recovered. (1) The recovery of CaCo3 was attempted by adding #m H2SO4 instead of 3M HCL to the SiO2/ CaCO3 residue. (2) The recovery of CaCO3 was attempted by adding 1M KNO3 solution instead of 1M K2CO3 solution to the filtrate, containing aqueous CACl2
