I have just answered this question as part of homework myself, limewater is a common name for Ca(OH)2 (calcium hydroxide) and when limewater and carbon dioxide meet they instantly react in a visible way. The limewater turns cloudy, sort of like when milk and water meet.
Hope this helps
When carbon dioxide reacts with lime water (calcium hydroxide solution), it forms a white precipitate of calcium carbonate. This reaction is commonly used as a test for the presence of carbon dioxide gas.
take the gas atach it to the flask with limewater....if carbon dioxide is present then it will turn cloudy...thats the answer for test of carbon dioxide i think the answer your looking for is bromthymol blue
CaCO3 (s) + H2O(l) CaCO3 is a white solid that appears cloudy in solution Limewater is also used in the chemical test for carbon dioxide. The chemical test is if carbon dioxide is mixed with limewater it then clouds. If this happens then the gas will be carbon dioxide.
Limewater is a solution made of Calcium Hydroxide and water. Calcium Hydroxide is found in things like oyster shells and bird eggs. There are many uses including food preparation, creating paint and topical medicines.
The limewater is filtered so that the undissolved particles of calcium hydroxide do not make the limewater solution cloudy even before it is used to test for carbon dioxide gas. By filtering it, the limewater solution is made clear and colorless, which makes it easier to notice it becoming cloudier when carbon dioxide gas is bubbled through it.
Solid calcium hydroxide is used to test for carbon dioxide because it reacts with carbon dioxide to form calcium carbonate. This reaction causes the solution containing calcium hydroxide to turn cloudy, allowing us to confirm the presence of carbon dioxide.
Calcium hydroxide is used to test for carbon dioxide because the product of the reaction, calcium carbonate, is insoluble, and easily visible.
When carbon dioxide reacts with lime water (calcium hydroxide solution), it forms a white precipitate of calcium carbonate. This reaction is commonly used as a test for the presence of carbon dioxide gas.
Calcium ydroxide is just another word for "Limewater". Limewater turns milky in the presence of Carbon Dioxide.
The precipitate formed is Calcium Carbonate (CaCO3).
A positive test for carbon dioxide is the limewater test. When carbon dioxide gas is bubbled through limewater, it turns milky or cloudy due to the formation of a white precipitate of calcium carbonate.
When limewater (calcium hydroxide solution) reacts with carbon dioxide, it forms a white precipitate of calcium carbonate. This is a chemical reaction that is often used to test for the presence of carbon dioxide gas.
When carbon dioxide is treated with limewater (calcium hydroxide solution), a white precipitate of calcium carbonate forms. This is a chemical reaction that is commonly used to test for the presence of carbon dioxide gas.
To test for carbon dioxide, you can bubble the gas through limewater (calcium hydroxide solution). If carbon dioxide is present, it will cause the limewater to turn milky or cloudy due to the formation of calcium carbonate. Another method is using a pH indicator like bromothymol blue, which will change color in the presence of carbon dioxide.
Bubble the gas through limewater (calcium hydroxide), and then a white precipitate is formed, which is actually calcium carbonate.
Carbon dioxide form a milky suspension of calcium carbonate in calcium hydroxide; hydrogen doesn't react. But hydrogen react with oxygen when a flame exist.
Limewater (calcium hydroxide) react with carbon dioxide and form insoluble, white precipitate of calcium carbonate.
