Chemical Compounds, Electrovalent, Covalent


This article aims to distinguish compounds that have electrovalent and covalent bonds and distinguish between complex and non-complex formation reactions. This method by observing through the materials used in this experiment are NaCl, AgNO3, CHCl3, KCNS, CH3COOH, CCl4, C2H5OH, K3Fe (CN) 6, HCl, methyl orange (MO), BaCl2, K4Fe (CN) 6, CuSO4, NH4OH, and FeCl3. The results of the observations found a difference between complex and non-complex compounds. When mixed with KCNS, they can react which is indicated by a change in color, while non-complex compounds cannot react. The equation between ethanol solution and CHCl3, if each solution is added AgNO3 will produce a covalent compound, but the change is different where ethanol is added to AgNO3 to become cloudy white, while CHCl3 does not react.
