Khimiia 10 Klass: Rudzitis 2 Prakticheskaia Rabota

The primary goal of this experiment is to use qualitative chemical reactions to identify unknown organic substances in test tubes, such as . 2. Prepare Reagents and Equipment

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: khimiia 10 klass rudzitis 2 prakticheskaia rabota

Below is a structured report (essay-style) for this practical work. 1. Define the Objective The primary goal of this experiment is to

This indicates the presence of multiple hydroxyl ( −OHnegative cap O cap H ) groups on adjacent carbon atoms. Step C: Identifying Aldehydes or Glucose Add a drop of litmus or a small

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