2.2 Qualitative Analysis

-Introduction 

Qualitative analysis in chemistry is a branch of analytical chemistry that focuses on identifying and characterizing the components of a sample without necessarily determining their exact quantities. This type of analysis is particularly useful when you want to identify the presence or absence of specific substances in a sample rather than quantifying their amounts. In this Internal standard, Qualitative analysis will be used to identify unknown substances in a sample. By employing various chemical tests and analytical techniques, you can determine the presence of specific ions or compounds.

Key things to check if you balanced the equations correctly:

1: The number of atoms: Make sure you count the number of each type of atoms on both sides and they should be the same number on both.

2: The charge: calculate the sum of the charge on both sides and they should be equally charged.
