Qualitative analysis

Purpose: To testing of a centerfield or mixture and hold in its chemical constituents, to develop a systematic scheme by apply the material attached to us to identify the queer solutions. Material: Copper(II)Sulfate (0.1mol/L) Ammonium sulfate (0.1mol/L) Copper(II) treat (0.1mol/L) Zinc sulfate (0.1mol/L) Barium chloride (0.1mol/L) 4 unknown solutions Sodium Carbonate (0.1mol/L) Procedure: 1.         2 drops of CuSO4 was added with 2 drops of each of BaCl2, ZnSO4, (NH4)2SO4 and NaCO3 in separate test tubes. 2.         2 drops of Cu(NO3)2 was added to 2 drops of each of BaCl2, ZnSO4 and (NH4)2SO4 in separate test tubes. 3.         2 drops of Na2CO3 was added with 2 drops of each of BaCl2, ZnSO4, (NH4)2SO4 and NaCO3 in separate test tubes. 4.         2 drops of unknown solution # 1 was added with 2 drops of each of CuSO4, Cu(NO3)2 and NaCO3 in separate test tubes. 5.         2 drops of unknown solution # 2 was added with 2 drops of each of CuSO4, Cu(NO3)2 and NaCO3 in separate test tubes. 6.         2 drops of unknown solution # 3 was added with 2 drops of each of CuSO4, Cu(NO3)2 and NaCO3 in separate test tubes. 7.         2 drops of unknown solution # 4 was added with 2 drops of each of CuSO4, Cu(NO3)2 and NaCO3 in separate test tubes.

Conclusion: Qualitative digest is to describe a smelling or change in matter that has no bit value expressed. E.g.) changing in colour throw reaction, the conductivity test of electrolytes. We conclude that qualitative analysis is often hire for diagnostic testing. Also we knows how could we determine which ions were present by use the qualitative analysis. We conclude that it is life-threatening to identify an ion in a solution unless it dos a compound with low solvability to form a decrease and recognize that the absence of...
