What is lime water observed?

Reaction with limewater Carbon dioxide reacts with limewater (a solution of calcium hydroxide, Ca(OH) 2), to form a white precipitate (appears milky) of calcium carbonate, CaCO 3.

How is lime water prepared in the laboratory?

How to Make the Solution

  1. Put 1 teaspoon of calcium hydroxide in a clean glass jar, up to 1 gallon in size.

Calcium hydroxide, also called slaked lime, Ca(OH)2, is obtained by the action of water on calcium oxide. When mixed with water, a small proportion of it dissolves, forming a solution known as limewater, the rest remaining as a suspension called milk of lime.

What is the use of lime water?

Drinking lime water improves digestion. Limes are acidic and they help saliva break down food for better digestion. Additionally, flavonoids in limes stimulate secretion of digestive juices. If you experience constipation, the acidity of limes can clear the excretory system and stimulate bowel activity.

Why is lime water is used in the experiment carbon dioxide is produced during respiration?

Answer: As lime water turns milky when Carbon Dioxide is dissolved in it, it can be used to detect the presence of Carbon Dioxide which is released during respiration by germinating seeds.

What do you observe when air is passed into lime water suggest suitable reasons for the observation what type of reaction is it?

When exhaled air is blown through Lime Water which is also known as calcium hydroxide, the carbon dioxide present in the exhaled air reacts with the Lime water and turns it into a milky solution, since the the CO2 reacts with Ca(OH)2 and forms CaCO or Calcium Carbonate, which is insoluble and white in colour.
