What is the chemical formula of lime-water?
The chemical formula of lime-water is Ca(OH)2, which is calcium hydroxide.
Is lime water a chemical reaction?
Lime water is not a chemical reaction by itself. It is a solution of calcium hydroxide in water, where the calcium hydroxide has dissolved to form calcium ions and hydroxide ions. When lime water reacts with carbon dioxide in the air, it forms calcium carbonate, which is a chemical reaction.
What is the chemical test to show that a gas is carbon dioxide?
Put the gas (CO2) in lime water. If the lime water changes colour, then it means that there is carbon dioxide in the gas depending on how fast the lime water changes colour
What is the chemical name of lime water?
calcium hydroxide (Ca(OH)2)
What causes concrete to harden?
Chemical reaction of lime and dehydrated gypsum with water.
What is the difference between slaked lime and lime water?
When you slake a lime an leave it for a few months, there will be a layer of water (providing you used a sufficient amount) ontop of the slaked lime putty. this water is limewater and is clear but contains tiny particles in suspension. The putty is what we refer to as slaked lime.
What is the chemical compound found in slaked lime?
The chemical compound found in slaked lime is calcium hydroxide, which is produced by adding water to calcium oxide (quicklime). It is commonly used in construction, agriculture, and water treatment applications.
What gas burns with a pop in lime water?
Carbon dioxide gas burns with a pop in lime water. When carbon dioxide gas is passed through lime water, it forms a milky precipitate of calcium carbonate, resulting in the pop sound due to the chemical reaction.
How is slake lime made?
adding water to quick lime produces slaked lime.
What chemical test could be used to confirm that the gas prodced in a chemical reaction is carbon dioxide?
The gas yielded from a chamical reaction should be allowed to pass through clean lime water. If the gas is CO2, it turns lime water milky by formation of CaCO3. This is the confirmatory test for CO2 gas
Why is slaking of lime regarded as a chemical change?
Slaking of lime is considered a chemical change because it involves a chemical reaction. When water is added to quicklime (calcium oxide), it reacts exothermically to form slaked lime (calcium hydroxide), releasing heat. The chemical composition of the substance changes during this process, demonstrating a chemical change.
How do you get slaked lime from seashells?
the only way to get slaked lime is by burning the sea shells in a lime kiln then by adding cold water, this chemical reaction is by burning the carbon off from the calcium then replaced by oxygen atoms, this process will make the seashell lighter , when cold water is added this process will break down the seashell, then turn into hydrated lime.
