Concentrated H2SO4 Test Simulator

Preliminary Test: Conc. H2SO4

Qualitative Salt Analysis - Identifying Acidic Radicals (Cl⁻, Br⁻, I⁻, NO₃⁻) via Gas Evolution.

1. Setup Experiment

Select Unknown Salt

2. Observation

Visible Gas/Fumes None
Status: Standby.
Select a solid salt. Thick, concentrated Sulfuric Acid will be added and gently heated. Caution: Corrosive and oxidizing!

3. Chemical Principles

Concentrated Acid Group: Includes Chloride, Bromide, Iodide, Nitrate, and Oxalate.

Displacement & Oxidation: Conc. H2SO4 is a strong, non-volatile acid that displaces volatile acids (like HCl or HNO3) from their salts. For Br⁻ and I⁻, H2SO4 also acts as an oxidizing agent, oxidizing them to free Br2 (brown gas) and I2 (violet gas).
