Ravi prepared carbondioxide using baking soda and vinegar. Carbondioxide changed lime water into milky white. Represent this experiment in a diagram with labelling.

Carbondioxide turns lime water into milky white due to the formation of______

___gas changes the colour of lime water into milky white.

Observe the above diagram and answer the following questions : Why the lime water is used in this experiment ?

When carbondioxide gas is passed through lime water, the following changes are observed.

Rearrange the following sentences in a correct order (i)You observe bubbles coming out with a hissing sound. Pass this gas through freshly prepared lime water(ii)Carbondioxide and Calcium Carbonate are formed. Hence it is a chemical change(iii)Take a tea spoon of vinegar in a test tube and odd a pinch of baking soda to it(iv)Lime water changes to milky white showing that the gas sent into the test tube is carbondioxide

We can use lime water to test the presence of CO_2 in respiration experiments. What change do you observe in lime water ?

Observe the above diagram and asnwer the following questions. observe the above diagram and answer the following questions. Why boiled and cooled glucose is covered with paraffin. What is the use of adding diazine green to glucose solution ? What change you notice in glucose solution? Why lime water is used in this experiment. Why bulb of thermometer is dipped in the glucose water.

Likitha made an experiment that CO_2 is liberated during respiration. But the lime water in it do not changed to milky white what is the error made by her?

Chemical A is used for water softening to remove temporary hardness. A reacts with sodium carbonate to generate caustic soda. When carbondioxide is bubbled through A, it turns cloudy. What is the chemical formula of A?

Take vinegar, lemon juice, soapy water, baking soda in different vessels. Pur beetroot pieces in the vessels. Predict what happens. Verify your prediction by observing the changes. After 10 minutes, 30 minutes, 60 minutes record your observations. What do you conclude?
