What is the chemical formula of lime-water?
Ca(OH)2
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 chemical do you use to identify carbon dioxide?
lime water is the name of the experiment...
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 kind of reaction occurs when sulphur dioxide reacts with lime water?
A chemical change. CaSO3 is insolube in water.
How do you perform the lime water test?
Lime water turns milky when CO2 (carbon dioxide) is passed through it. So to test if a given liquid is lime water, pass CO2 through it, if it turns milky, then it is limewater. You can reverse this chemical reaction by putting vinegar in it.
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
Is lime water a chemical reaction?
Yes, as limewater is liquid slaked lime if I recall correctly. And if carbon dioxide reacts with limewater, it turns cloudy.
When few pieces of marble is dropped in dilute hydrochloric acid the evolved gas passed through lime water what change would be observed in lime water so what will be the balanced chemical equation?
The chemical equation is:Ca(OH)2 + CO2 = CaCO3 + H2O
Chemical equation to make iron phosphate?
Iron heated with lime water produces iron phosphate
Why is calcium hydroxide and limewater caOH2?
Ca(OH)2 is Calcium hydroxide (by chemical name), also known as lime, slaked lime, slack lime or pickling lime (by trivial and geological name)Limewater is the name of saturated solution of it in water.
