What color does hydrogen chloride turn damp litmus paper?
turns blue litmus paper red
What test can be used to confirm the presence of ammonia gas?
1. It has a pungent smell 2. direct the gas to a damp red litmus paper. If the litmus paper turns blue, it is ammonia gas
Does ammonia turn litmus paper blue or red?
No, it shouldn't...AgNO3 has a neutral pH of 6, so the paper probably won't change colors.
Is chlorine gas an acidic or alkaline gas?
It is a neutral gas that bleaches damp litmus paper. Gases themselves are not acidic/alkaline, it is only when they are combined with hydrogen ions (Hence the damp litmus paper) that they become acidic/alkaline and in this case acidic.
What is the test for Chlorine Gas?
You take a damp blue litmus paper and put in through lime water.the lime water will go red but after a while it will bleach it white.
What effect has hydrogen chloride gas on damp litmus papaer?
Turns it red then bleaches it.
What happens to red litmus paper if dipped in water?
A bleaching agent turns litmus paper white. For example, chlorine gas turns damp blue litmus paper red, and then bleaches, making it white.
What happens when fluorine is exposed to damp blue litmus paper?
When chlorine comes in contact with litmus paper it bleaches it, so it turns white. Before it turns white, though, it can turn pink because of the acids formed when chlorine reacts with water. Cl2 + H2O -> HOCl + HCl Not sure about the effect of other halogens on damp, blue litmus paper, but I suspect that similar reactions would occur.
What color does hydrogen chloride turn damp litmus paper?
turns blue litmus paper red
Why does the litmus paper need to be damp?
so that the gas can dissolve onto it
How do you test for ammonia gas?
The most common way is to place a damp red litmus paper near it. It turns blue if the gas is ammonia.Place a damp red litmus paper over the mouth of the test tube. Ammonia gas turns damp red litmus paper blue. Ammonia also has a pungent odour.Ammonia turns red litmus into blue.It also emmits a white gas with HCl.
What color does hydrogen sulphide turn damp litmus paper?

Does ammonia turn litmus paper blue or red?
No, it shouldn't...AgNO3 has a neutral pH of 6, so the paper probably won't change colors.
How can you test for ammonia?
hold a damp piece of red litmus over an open container of ammonia if the gas is present the paper will turn blue
Why must litmus paper used to observe gas be moist?
Litmus paper is used moist to obtain the desired result. Litmus responds different to dry and wet conditions depending on the chemicals being checked.
Is chlorine gas an acidic or alkaline gas?
It is a neutral gas that bleaches damp litmus paper. Gases themselves are not acidic/alkaline, it is only when they are combined with hydrogen ions (Hence the damp litmus paper) that they become acidic/alkaline and in this case acidic.
