This is the same principle as to carbon dioxide:
Calcium sulfite is insoluble, thus precipitating, in saturated Ca(OH)2 solution.
Ca2+ + 2 OH- + SO2,gas --> CaSO3,precip. + H2O
Compare:
Ca2+ + 2 OH- + CO2,gas --> CaCO3,precip. + H2O

What happens when sulfur dioxide is dissolved in water?
it turns to sulphourus acid. SO2+H2O-->H2SO3
How would you use lime water to test if there is carbon dioxide in your exhaled breath?
when lime water react with carbon dioxide,it turns milky.So, we have to take some lime water in a test tube and exhale 2 -3 times to the test tube through a bend tube. It will turn milky and that's why our exhaled breath is carbon dioxide.
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 happens when carbon dioxide gas is passed through lime water?
It turns cloudy (or milky). Lime water is calcium hydrogen carbonate dissolved in water. When it comes into contact with carbon dioxide, they react together to make calcium carbonate (chalk), which is white and less soluble in water. So the fine white precipitate that forms makes the solution turn cloudy.
Identification of carbon dioxide?
To check for carbon dioxide there is this tests. Pass the gas through lime water (saturated Ca(OH)2 solution). If it turns milky, then the gas is carbon dioxide.
What turns milky when carbon dioxide is present?
lime water
What is the effect carbon dioxide in lime water?
Lime water turns milky when carbon dioxide is added to it.Lime water also turns into Calcium carbonate (Limestone) solution
When carbon dioxide is passed though lime water is turns milky due to the formation fill in the blank?
Turns milky due to the formation of calcium bicarbonate. That is insoluble in water & look milky.
When testing for carbon dioxide the liquid should turn?
Water turns milky.
How do you text for carbon dioxide?
lime water (calcium hydroxide) turns milky when carbon dioxide is present
What gas turns lime water milky white?
carbon dioxide CO2
What happen when carbon dioxide is bubbled in lime water in small amount?
The lime water turns milky
What is the standard test for CO2?
Get a test tube filled with lime water, then breathe into the test tube and if the lime water turns a milky white colour then there is carbon dioxide present!
What happens when sulfur dioxide is dissolved in water?
it turns to sulphourus acid. SO2+H2O-->H2SO3
What happens when carbon di oxide passes through lime water?
Carbon dioxide turns lime water milky.
How do you test if the liquid is lime water?
Lime water turns milky when CO2 (carbon dioxide) is passed thru it. So to test if a given liquid is lime water, then pass CO2 thru it, if it turns milky, d liquid is lime water...
Is there naturally sulfur dioxide in water?
No sulfur dioxide is not present naturally. It pollutes the water.
