2 Prakticheskaia Rabota — Khimiia 10 Klass Rudzitis

Carboxylic acids can be identified by their acidity or their reaction with carbonates. Add a drop of litmus or a small amount of Na2CO3cap N a sub 2 cap C cap O sub 3 to the sample. Observation: Litmus turns red; Na2CO3cap N a sub 2 cap C cap O sub 3 produces effervescence (bubbles of CO2cap C cap O sub 2 Equation:

In the 10th-grade chemistry curriculum by Rudzitis and Feldman, Practical Work No. 2 typically focuses on the This work is designed to apply qualitative analysis to distinguish between various classes of organic substances. Add and heat the mixture gently

The blue precipitate dissolves, forming a bright blue (cornflower blue) transparent solution.
