It is a weak acid and it is in an aqueous form, i.e., it is a water solution.

Limewater and reaction results in a carbonic acid. When carbon dioxide reacts with water, it dissolves, while some of it reacts with water molecules to generate an acidic solution known as carbonic acid. What is the reaction between carbon dioxide and water? As this solution evaporates, the reverse reaction occurs which results in the formation of stalagmites and stalactites. The naturally occurring acid rain chemically erodes the limestone and results in the formation of a cave. This reaction shows another phenomenon that we may have seen in our daily lives. How does carbon dioxide turns lime water milky? The solution of calcium hydroxide is limewater and if carbon dioxide bubbles through the limewater, it turns cloudy white or milky. When carbon dioxide reacts with lime water (calcium hydroxide solution), a white precipitate of calcium carbonate is produced. One of the most effective ways to test for carbon dioxide gas is the limewater test. Now, we will answer how to test for carbon-dioxide. What happens when you mix carbon dioxide and lime water? Written as an Equation This chemistry is important in understanding how hard water is formed and then limescale is formed in kettles and hot water boilers. This happens as the carbon dioxide forms acidic carbonic acid when it dissolves in the water, the carbonic acid (H2CO3) reacts further with the calcium carbonate. Bubbling carbon dioxide through the solution for an extended period of time makes the solution become clear and colorless. This is because chalk is precipitating in the limewater. The characteristic carbon dioxide test, is checking that the limewater is milky. The white milky suspension/precipitate is caused by the formation of calcium carbonate. The appearance of this solid makes the liquid appear ‘milky’. Calcium carbonate is chalk, and when it is produced, it precipitates and solid particles of chalk appear. The carbon dioxide and limewater react to produce water in addition to the calcium carbonate. What happens when Lime Water reacts to Carbon Dioxide?Ĭarbon dioxide reacts with limewater to form calcium carbonate, which precipitates out of the solution. In this article, we have answered all the questions related to the reaction of lime water and. But one of its most noteworthy property is that it is used to absorb carbon dioxide from the air. Limewater is an aqueous solution of slaked lime and you will find it in antacids, medicines and lotions. You may be wondering what is lime water used for. Carbon dioxide is the only gas that turns lime water cloudy.

You may often come across a question 'What gas turns limewater cloudy?' The answer to this question is well known.
