Openchemistry/Qualitative Analysis

= What is Qualitative Analysis? =

Qualitative: This is to do with te quality of something. Answering, what is in the solution?

Analysis: detailed looking (examination) to determine what something is.

In chemistry this is a fancy way for us to say, "we are finding out what ions are in this solution". There are a few terms that are helpful to understand and some easier faster ways to say what is happening.

Solubility

 * 1) Define the terms solute, solvent, solution, solubility and saturated.
 * 2) Describe in detail the dissolving process and account for the changes which occur.
 * 3) Write the equations showing the solvation of ionic solutes in water and know that this is not a chemical reaction.
 * 4) Recall the solubility rules for nitrates, sulfates, carbonates, hydroxides, oxides, chlorides, and sodium, potassium and ammonium compounds.
 * 5) Write net ionic equations for precipitation reactions.
 * 6) Know the tests which characterise the following ions: Ag+, Mg2+, Cu2+, Pb2+, Al3+, Fe3+, Cl-, I-, SO42-, CO3undefined2-
 * 7) Identify the ions contained in unknown solutions by carrying out a logical sequence of tests.
 * 8) Know what a complex ion is and how one is formed.
