What colour will limewater turn if carbon dioxide is added?
Limewater will turn milky white when carbon dioxide is added to it due to the formation of calcium carbonate.
Why is mineral oil added to the vial containing limewater?
Mineral oil is added to the vial containing limewater to prevent the absorption of carbon dioxide from the air. This helps to maintain the limewater solution saturated with calcium hydroxide, which is necessary for its intended use in chemical experiments or tests.
Why double or triple bonds are unsaturated compounds?
Double and triple bonds are considered unsaturated because they contain fewer hydrogen atoms than their saturated counterparts, which only have single bonds. In a saturated compound, every carbon atom is bonded to as many hydrogen atoms as possible, whereas the presence of double or triple bonds means that some hydrogen atoms are replaced by additional carbon-carbon bonds. This characteristic allows unsaturated compounds to undergo reactions such as hydrogenation, where additional hydrogen can be added to convert them into saturated compounds.
What substance is added to an organic molecule to test for the degree of saturation?
Bromine or potassium permanganate is added to an organic molecule to test for the degree of saturation. These reagents react differently with saturated and unsaturated compounds, producing distinct color changes or precipitates that can be used to identify the degree of saturation.
Why are transition metal compounds added to glazes?

What happens when a crystal of solute is added to a unsaturated solution?
It will dissolve
What happens when a solute is added to an unsaturated solution?
It will dissolve in the solution.

What can you see when bromine water is added to an unsaturated organic compound?
When bromine water is added to an unsaturated organic compound, the solution will turn from orange to colorless as the bromine reacts with the double bonds in the compound. This reaction is a test for unsaturation in organic molecules, as saturated compounds do not react with bromine water in the same way.
Why double or triple bonds are unsaturated compounds?
Double and triple bonds are considered unsaturated because they contain fewer hydrogen atoms than their saturated counterparts, which only have single bonds. In a saturated compound, every carbon atom is bonded to as many hydrogen atoms as possible, whereas the presence of double or triple bonds means that some hydrogen atoms are replaced by additional carbon-carbon bonds. This characteristic allows unsaturated compounds to undergo reactions such as hydrogenation, where additional hydrogen can be added to convert them into saturated compounds.
What can you see in limewater if there is oxygen in it?
If there is oxygen in limewater, it would stay clear. Limewater (calcium hydroxide solution) is typically used to detect the presence of carbon dioxide. If carbon dioxide is present, it forms a white precipitate of calcium carbonate, turning the limewater cloudy or milky.
What will happen when a crystal of solute is added to an unsaturated solution?
It will dissolve
What happens when bromine water is added to oil?
When bromine water is added to oil, if the oil contains unsaturated bonds, the reddish-brown color of the bromine water will be reduced as the bromine molecules add across the double bonds in a chemical reaction called bromination. This reaction is used to test for the presence of unsaturation in organic compounds like alkenes or alkynes.
What happens when 1 drop of bromine is added to vegetable oil?
When 1 drop of bromine is added to vegetable oil, a chemical reaction occurs where the bromine reacts with the unsaturated fats in the oil. This reaction causes the bromine to decolorize, turning from reddish-brown to colorless. This change is a test for the presence of unsaturated fats in the vegetable oil.
Is saltwater solution saturated or unsaturated?
From your question it is impossible to tell. A salt-water solution can be unsaturated or saturated depending on how much salt was added.
What substance is added to an organic molecule to test for the degree of saturation?
Bromine or potassium permanganate is added to an organic molecule to test for the degree of saturation. These reagents react differently with saturated and unsaturated compounds, producing distinct color changes or precipitates that can be used to identify the degree of saturation.
