Qualitative analysis

Purpose: To testing of a substance or mixed bag and insure its chemical constituents, to develop a systematic schema by apply the material given to us to recognize the stranger 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 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 adjourn test tubes. 2.         2 drops of Cu(NO3)2 was added to 2 drops of each of BaCl2, ZnSO4 and (NH4)2SO4 in smash test tubes. 3.         2 drops of Na2CO3 was added with 2 drops of each of BaCl2, ZnSO4, (NH4)2SO4 and NaCO3 in discriminate test tubes. 4.         2 drops of isolated solution # 1 was added with 2 drops of each of CuSO4, Cu(NO3)2 and Na CO3 in crock up test tubes. 5.         2 drops of unknown solution # 2 was added with 2 drops of each of CuSO4, Cu(NO3)2 and NaCO3 in discontinue 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 have reaction, the conduction test of electrolytes. W e conclude that qualitative analysis is a g! ood deal utilize 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 dos a compound with low-pitched solubility to form a precipitate and recognize that the absence seizure of...
