Qualitative analysis

Purpose: To testing of a substance or multifariousness and insure its chemical constituents, to develop a systematic dodge by apply the material given to us to describe the stranger solutions. Material: Copper(II)Sulfate (0.1mol/L) Ammonium sulfate (0.1mol/L) Copper(II) nitrate (0.1mol/L) surface sulfate (0.1mol/L) Barium chloride (0.1mol/L) 4 occult solutions Sodium change (0.1mol/L) Procedure: 1.         2 drops of CuSO4 was added with 2 drops of each of BaCl2, ZnSO4, (NH4)2SO4 and NaCO3 in spot test tubes. 2.         2 drops of Cu(NO3)2 was added to 2 drops of each of BaCl2, ZnSO4 and (NH4)2SO4 in signalize test tubes. 3.         2 drops of Na2CO3 was added with 2 drops of each of BaCl2, ZnSO4, (NH4)2SO4 and NaCO3 in mark test tubes. 4.         2 drops of obscure solution # 1 was added with 2 drops of each of CuSO4, Cu(NO3)2 and NaC O3 in severalise test tubes. 5.         2 drops of unknown solution # 2 was added with 2 drops of each of CuSO4, Cu(NO3)2 and NaCO3 in give 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 analysis is to describe a smell or change in matter that has no numeral value expressed. E.g.) changing in colour deteriorate reaction, the conduction test of electrolytes. We conclude that qualitative analysis is very muc h utilize for diagnostic testing. Also we k! nows 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 dos a compound with pathetic solubility to form a precipitate and recognize that the absence seizure of...
