摘要：

K2SO4 was obtained by reacting KCI with MgSO4 using stoichiometric amts. of reagents or excess of KCI. The aq. soln. of KCI and MgSO4 was slowly evaporated for 48 h at 20 degrees C. The obtained crystals and the filtrate were analyzed for the content of Cl , SO42-, K+ and Mg2+ ions. The use of KCI in excess in relation to the reaction stoichiometry allowed to obtain chloride-free K2SO4 with the yield of 45.6%.
