Qualitative Analysis: Identifying Anions and Cations

Qualitative analysis involves forming and decomposing complex ions. Qualitative tests are very sensitive, allowing to detect a very small amount present in sample. Due to sensitivity, cleaning utensils and accurate observations are essential to results. Many basic principles are applied to determine the impurities or cations. To determine which impurities are present, scheme or flow chart is ...
