Question

You are provided with a sample of Ethanoic acid in a test tube .what would you observe while

studying it’s effect on red litmus, blue litmus and powdered sodium hydrogen carbonate ? state

briefly .​

Answer 1

• Ethanoic acid reacts with red litmus paper to convert it into the colour of blue.
• Since ethanoic acid is not a base, it does not reacts with Blue Litmus Paper.
• When sodium hydrogen carbonate reacts with ethanoic acid, it gives sodium ethanoate, carbon dioxide and water. reaction can be represented by the following equation :

CH3COOH + NaHCO3 -------> CH3COONa + CO2 + H2O

Answer 2

Answer:

blue litmus- red

red litmus- red

sodium hydrogen carbonate- evolution of CO2 gas.

Explanation

Acids turn blue litmus red and do not change the color of red litmus.

When in contact with sodium hydrogen carbonate, carbon-dioxide gas is formed and water is produced.
