Reaction between glucose and copper oxide with lime water?
When glucose reacts with copper oxide in the presence of lime water, a redox reaction occurs where glucose is oxidized to produce carbon dioxide and water. The copper oxide is reduced to copper metal. The lime water is not directly involved in the reaction but can be used to test for the presence of carbon dioxide produced in the reaction.
What is the reaction of slaked lime with carbon dioxide?
When slaked lime reacts with carbon dioxide, it undergoes a chemical reaction to form calcium carbonate, water, and heat. This process is known as carbonation and is commonly used in industries such as construction and water treatment for its ability to solidify and stabilize materials.
Is lime water an oxidizer?
The most common lime water reaction is with carbon dioxide, denoted by the equation: Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l) Since this is not a redox reaction (no oxidation numbers change), lime water is not an oxidizer.
What kind of reaction occurs when sulphur dioxide reacts with lime water?
When sulfur dioxide reacts with lime water (calcium hydroxide), calcium sulfite is formed. This reaction involves the neutralization of sulfur dioxide, leading to the formation of a white precipitate of calcium sulfite. This reaction is the basis for using lime water as a method to detect the presence of sulfur dioxide gas.
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.
What causes concrete to harden?
Chemical reaction of lime and dehydrated gypsum with water.

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

What happens when acid react with compounds made of carbonate?
When acids react with carbonates, carbon dioxide is produced. You can test this by waiting for the chemical reaction to take place and then using a bung to insert the gas into lime water!

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.
When water is added to lime it expands and gets extermly hot what can you tell from this?
The reaction between water and lime is exothermic, meaning it releases heat. This is due to the chemical reaction that occurs when water reacts with lime to form calcium hydroxide. The expansion is a result of the heat generated in the reaction causing the water to evaporate and create steam.

What chemical reaction happens when lime and acid is combined?
When lime (calcium hydroxide) is combined with an acid, a neutralization reaction occurs resulting in the formation of water and a salt. The calcium in lime reacts with the acid to form calcium ions, while the hydrogen ions in the acid combine with the hydroxide ions in the lime to form water.
How is slake lime made?
adding water to quick lime produces slaked lime.
