Question

procedure and precautions to perform and observe the action of water on quicklime and

Answer 1

PROCEDURE:

1. Wash a borosil beaker with distilled water and dry it.
2. Wash a borosil beaker with distilled water and dry it.Take a small amount of calcium oxide (quick lime) and slowly add water to it.
3. Wash a borosil beaker with distilled water and dry it.Take a small amount of calcium oxide (quick lime) and slowly add water to it.Wash and take a clean glass rod to stir the mixture of quick lime and water.
4. Wash a borosil beaker with distilled water and dry it.Take a small amount of calcium oxide (quick lime) and slowly add water to it.Wash and take a clean glass rod to stir the mixture of quick lime and water.Touch the beaker carefully from outside.
5. Wash a borosil beaker with distilled water and dry it.Take a small amount of calcium oxide (quick lime) and slowly add water to it.Wash and take a clean glass rod to stir the mixture of quick lime and water.Touch the beaker carefully from outside.Observe the change.
6. Wash a borosil beaker with distilled water and dry it.Take a small amount of calcium oxide (quick lime) and slowly add water to it.Wash and take a clean glass rod to stir the mixture of quick lime and water.Touch the beaker carefully from outside.Observe the change.With the help of dropper take a few drops of the mixture from the beaker and place it on red and blue litmus paper strips.
7. Wait and observe.

PRECAUTION :

1. Take a small amount of compound such as quick lime to perform the experiment.
2. Take a small amount of compound such as quick lime to perform the experiment.Since the reaction is exothermic avoid touching the mixture directly.
3. Take a small amount of compound such as quick lime to perform the experiment.Since the reaction is exothermic avoid touching the mixture directly.Carefully pour water to the borosil beaker containing calcium oxide (quick lime).
4. Take a small amount of compound such as quick lime to perform the experiment.Since the reaction is exothermic avoid touching the mixture directly.Carefully pour water to the borosil beaker containing calcium oxide (quick lime).Calcium oxide causes severe burns and therefore it should be handled with a spatula.Use good quality glass beaker during the experiment because if the beaker is of poor quality then there are chances of crack on the beaker due to the exothermic reaction.
