Purpose: To testing of a substance or mixture and determine its chemical constituents, to develop a systematic scheme by using the material given to us to identify the unknown solutions. Material: Copper(II)Sulfate (0.1mol/L) Ammonium sulfate (0.1mol/L) Copper(II) nitrate (0.1mol/L) Zinc sulfate (0.1mol/L) Barium chloride (0.1mol/L) 4 unknown solutions Sodium Carbonate (0.1mol/L) Procedure: 1.<Tab/>2 drops of CuSO4 was added with 2 drops of each of …showed first 75 words of 336 total…

…showed last 75 words of 336 total…the conductivity test of electrolytes. We conclude that qualitative analysis is often used for diagnostic testing. Also we knows how could we determine which ions were present by using the qualitative analysis. We conclude that it is hard to identify an ion in a solution unless it forms a compound with low solubility to form a precipitate and recognize that the absence of a precipitate indicate that the ions being tested for is not present.
