Lime Water Experiment Concepts

The video demonstrates a fun experiment using lime water to show how carbon dioxide exhaled from our breath reacts with lime water to form a milky white solution. The presenter explains the materials needed, sets up the experiment, and highlights the chemical reaction between carbon dioxide and lime water. The experiment is conducted by blowing into two glasses, one with lime water and one without, to observe the difference. The video concludes with a summary of the results, proving the presence of carbon dioxide in exhaled air, and a prompt to subscribe.

What materials are required for the lime water experiment?

• A straw, a glass, lime water, and water

• A cup, a straw, soda, and salt

• A bottle, a funnel, milk, and sugar

• A spoon, a bowl, lemon juice, and vinegar

What gas do we exhale that reacts with lime water?

• Hydrogen

• Oxygen

• Nitrogen

• Carbon dioxide

What happens when carbon dioxide reacts with lime water?

• It changes the lime water to a green color

• It turns the lime water into a clear solution

• It makes the lime water bubble

• It turns the lime water milky white

Why does only one glass turn milky white in the experiment?

• Because both glasses have water

• Because only one glass has lime water

• Because both glasses have lime water

• Because only one glass has water

What does the experiment prove about the air we exhale?

• We exhale carbon dioxide

• We exhale nitrogen

• We exhale oxygen

• We exhale hydrogen
