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.
Why do you test with litmus paper?
The main use of litmus is to test whether a solution is acidic or alkaline. Wet litmus paper can also be used to test water-soluble gases; the gas dissolves in the water and the resulting solution colors the litmus paper. For instance, ammonia gas, which is alkaline, colors the red litmus paper blue. Chemical reactions other than acid-base reaction can also cause a color-change to litmus paper. For instance, chlorine gas turns blue litmus paper white - the litmus paper is bleached.[5] This reaction is irreversible and therefore the litmus is not acting as an indicator in this situation
How can you tell if the mixture is acidic or basic?
The simplest way is to use litmus paper. The mixture must be a liquid so that the mixture can react with the water and so dissociate into either hydronium or hydroxide ions. If it's a solid, try dissolving it in water. If you have a gas, use damp litmus paper. Red litmus paper is used to test for basic substances, and turns blue in a positive test. Blue litmus paper is used to test for acidic substances, and turns red in a positive test.
What changes red litmus to blue?
Ammonia gas, but so will any alkaline compound
Why a dry blue litmus paper is not affected by hydrogen chloride gas?
AS HCL DONATE ELECTRON IT HAS NO EFFECT ON DRY LITMUS PAPERType your answer here...
What colour does fluorine turn blue litmus?
I have done it before i turns blue litmus red
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.

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 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
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 gas is produced when moist blue litmus turn red?
Hydrogen chloride, HCl gas, making hydrochloric ACID with wet litmus paper.Wet litmus paper can be used to test water-soluble gases; the gas dissolves in the water and the resulting solution colors the litmus paper. For instance, ammonia gas, NH3 which is alkaline, colors the litmus paper blue. Acidicgases turn it red.

How would you find nature of gas?
we can test it through litmus paper if the nature of the gas is acidic the litmus will turn red and if it is basic litmus will turn blue.

What happens when sulphur dioxide dissolved in water is tested by blue litmus paper?
Burnt Magnesium ribbon ----> MgO (magnesium oxide)(basic in nature) When added to water, it forms its hydroxide MgO+H2O ----> Mg(OH)2 (which is a base) when added to litmus paper or litmus solution....it will give a light blue colour
Sodium is readily oxidized by oxygen gas if the product of the reaction were dissolved in water what would be the color the litmus for a litmus test?
Sodium is readily oxidized by oxygen gas. If the product of the reaction were dissolved in water, the color of the litmus for a litmus test would be blue. The red litmus paper will turn blue.
