Qualitative analysis is used to identify compounds. Those compounds are made of
cations and anions. These compounds can be in a single mixture. Therefore we have to follow a specified
procedure to identify these compounds
one by one. There are many different experiments to identify different compounds. In qualitative analysis, we observe
a physical change, when a reaction is being occurred or after completed the reaction.
In the qualitative analysis of inorganic chemistry in grade 12, we have some cations (positively charged ions) to identify such as Cu2+, Fe2+ and more.
As cations, there are few anions we have to learn in qualitative analysis in inorganic chemistry section.
Now we are going to see a small example which explains what is qualitative analysis and how it is done to identify cations and anions.
There are two brown colour solutions in two bottles. You have to identify these two solutions by doing some experiments. But you have informed that, these solutions contain ferric chloride (FeCl3) and ferric sulfate (Fe2(SO4)3). So you have to decide which bottle contains which compound.
