• 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
