Why water evaporates from a solution?
The water will evaporate leaving just the solids
What gas identified by bubbling it through lime water?
According to scientists, the type of gas that is identified when it bubbles in limewater is carbon dioxide because the solution turns cloudy in water.
Why does carbon dioxide affect lime water?
CO2 + Ca(OH)2 -> CaCO3 + H2OCarbon dioxide reacts with calcium hydroxide (lime water) to form calcium carbonate and water. Calcium carbonate is insoluble therefore exist in the form of a white precipitate which turns the solution cloudy.
How do you test for carbon dioxide?
to test for carbon dioxide is already dissolved in limewater, after this shake up the test tube, is it be that carbon dioxide is present then 2 things will happen: 1) the limewater will turn cloudy as CO2 is a precipatate is this solution 2) the limewater will begin to show efferevescence now we know gas is present If these 2 things happen then there is an extremely high chance that CO2 is present I hope this answers any questions about the test for C02 i hope this help remember dont skip school
What is the test for carbon dioxide?
to test for carbon dioxide is already dissolved in limewater , after this shake up the test tube , is it be that carbondioxide is present then two things will happen : 1) the limewater will turn cloudy as co2 is a precipatate is this solution 2)the limewater will begin to show efferevescence now we know gas is present if these two thing happen then there is an extremly high chance that co2 is present.
What do carbonates do when you add acid into them?
The carbonates will react with acid to form carbon dioxide, a gas which turns lime water cloudy, water, and a salt.
What gas is given off when it turns lemonade cloudy?
The gas given off when it turns lemonade cloudy is carbon dioxide. This is due to the formation of calcium bicarbonate which is insoluble.
What is the test for dioxide?
Bubbling through limewater. The gas is present if the limewater turns cloudy :)

If you collect gas from a dead animal and bubble it through lime water the lime water turns cloudy what is the gas?
CO2
How do you test a gas to see if it was carbon dioxide?
Bubbling the gas into limewater is the classic test for CO2. Limewater is a saturated solution of Ca(OH)2. When CO2 is dissolved it reacts to produce insoluble CaCO3 and the solution turns cloudy. Ca(OH)2(aq) + CO2(aq) --> CaCO3(s) + H2O(l) :)
What is observed when potassium bromide and sulphuric acid react?
H2 is formed which is a colourless gas but you can see bubbles. Br2 is also produced which is a dark orange/brown and turns the solution to this colour.
Does a solution appear cloudy?
A mixture that appears cloudy, heterogeneous, and has at least two substances visible is commonly called a suspension. A mixture that is cloud but uniform and homogeneous is called a colloid.
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.
What gas identified by bubbling it through lime water?
According to scientists, the type of gas that is identified when it bubbles in limewater is carbon dioxide because the solution turns cloudy in water.
Dry ammonia ga s has no action on litmus paper but a solution of ammonia in water turns red litmus to blue. why?
because when ammonia gas react with water it forms ammonia hydroxide which is a base so that it turns red litmus paper into blue
What test could you use to find out if CO2 gas is present in a small container?
Blow it through limewater. If the limewater turns "milky" or "cloudy" (a white substance is shown) then Carbon Dioxide is present. If nothing happens, then Carbon Dioxide is not present in your solution.
