Class 11 Chemistry Practical | Inorganic Qualitative Analysis (Salt no. 1) (Experiment 5)

Описание: Hey future chemists! 🧪 Welcome to Study With Mee, your new hub for high-scoring academic content. Welcome to Experiment No. 5 of our Class 11 Chemistry Practical series!

This video is an essential guide to *Inorganic Qualitative Analysis* or *Salt Analysis**. Our aim is to systematically identify the **Basic Radical (Cation)* and *Acidic Radical (Anion)* present in a given inorganic salt.

We walk you through all the necessary **Dry Tests**, starting with Preliminary observations like color and solubility[cite: 1866]. This foundational knowledge is crucial for proceeding to the more specific tests.

*What you will learn in this video:*
The three main stages of Salt Analysis: Preliminary, Cation Dry Tests, and Anion Dry Tests.
Performing *Dry Tests for Cations* (Basic Radicals), including:
Heating in a dry test tube (for decrepitation)[cite: 1867].
*Charcoal Cavity Test* and **Cobalt Nitrate Test**[cite: 1867].
The *Flame Test* using concentrated HCl on a platinum wire[cite: 1869].
Performing *Dry Tests for Anions* (Acidic Radicals), using:
Dilute HCl.
Concentrated $\text{H}_2\text{SO}_4$ (e.g., for Brown Gas evolution, suggesting $\text{NO}_3^-$).
Inferences drawn from observations (e.g., white crystalline salt suggests $\text{Pb}^{2+}$, $\text{Al}^{3+}$, $\text{Mg}^{2+}$, etc. are possibly present)[cite: 1866].
