Purpose: To testing of a nerve centre or mixture and get across its chemical constituents, to develop a systematic scheme by apply the material presumption to us to identify the weird solutions. Material: Copper(II)Sulfate (0.1mol/L) Ammonium sulfate (0.1mol/L) Copper(II) process (0.1mol/L) Zinc sulfate (0.1mol/L) Barium chloride (0.1mol/L) 4 unknown solutions Sodium Carbonate (0.1mol/L) Procedure: 1. Â Â Â Â Â Â Â Â 2 drops of CuSO4 was added with 2 drops of each of BaCl2, ZnSO4, (NH4)2SO4 and NaCO3 in separate test tubes. 2. Â Â Â Â Â Â Â Â 2 drops of Cu(NO3)2 was added to 2 drops of each of BaCl2, ZnSO4 and (NH4)2SO4 in separate test tubes. 3. Â Â Â Â Â Â Â Â 2 drops of Na2CO3 was added with 2 drops of each of BaCl2, ZnSO4, (NH4)2SO4 and NaCO3 in separate test tubes. 4. Â Â Â Â Â Â Â Â 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. Â Â Â Â Â Â Â Â 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. Â Â Â Â Â Â Â Â 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. Â Â Â Â Â Â Â Â 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 looking at or change in matter that has no issue value expressed. E.g.) changing in colour throw reaction, the conduction test of electrolytes. We conclude that soft analysis is often hold for diagnostic testing. Also we knows how could we study which ions were present by using the qualitative analysis. We conclude that it is gravely to identify an ion in a solution unless it dos a compound with low solvability to form a come and recognize that the absence of...
