Chemical analysis is a fundamental branch of chemistry concerned with the identification, separation, and quantification of the constituents within a substance or mixture. It employs a range of techniques and processes to determine both the composition and structural characteristics of a given sample.<\/p>\n
<\/p>\n
Chemical analysis is broadly divided into two categories:<\/p>\n
1. Qualitative Analysis<\/strong><\/p>\n 2. Quantitative Analysis<\/strong><\/p>\n <\/p>\n Common Techniques in Chemical Analysis<\/strong><\/p>\n <\/p>\n\n
