Question

(A) Air being passed into lime water with a pichkari, syringe. (B) Air being exhaled into lime water? Can you explain it berfily?

Answer 1

Answer:

mark me as brainliest

Explanation:

Air is exhaled through lime water and air is passed through lime water using pichkari. ... Lime water will turn milky first when air is exhaled through lime water because exhaled air contains a greater concentration of carbon dioxide than present in air.

Answer 2

Answer:

• Our exhaled air which is out from our mouth contains carbon di oxide and when it is passed through lime water the lime water turns milky

• Carbon di oxide which is given out from our mouth reacts with lime and forms calcium hydroxide

• This causes the lime water to turn milky and this solution is insoluble and it turns into milky solution

• In the first one no changes can be observed because pichkari contains very less amount of carbon di oxide than our mouth
