What effect does chlorine have on moist universal indicator?
Chlorine turns moist universal indicator paper red, then bleached. It has the same effect on blue litmus paper (red then bleached). this shows it is an acidic gas and so when reacts with sodium for example (an alkali metal) makes sodium chloride (salt).
Why is moist indicator paper used to test for ammonia gas?
Because it's a simple way of indicating presence of ammonia, since ammonia is Alkaline (base) means that Red litmus paper (ph indicator ) is a water soluble sum of dies turning from RED -> Blue, instead of purple (neutral PH). Wet medium is necessary to break gas into ions that will give u the result u need.
What colour would ammonia gas turn universal indicator paper?
Ammonia gas would turn universal indicator paper blue or purple depending on the concentration of ammonia present.
What do you see when chlorine is put with litmus or universal indicator paper?
When chlorine gas reacts with litmus paper, it will turn red litmus paper white and then dissolve it. When chlorine gas reacts with universal indicator paper, it will change the color to yellow due to its acidic nature.
What colour does fluorine turn blue litmus?
Fluorine does not have a specific color reaction with blue litmus paper, as it does not change the color of the paper. However, fluorine gas is highly reactive and can potentially react with the water in the litmus paper, causing bleaching or other color changes.

What effect does fluorine have on moist indicator paper?
Fluorine gas reacts with moisture in the air to form hydrofluoric acid, which would likely cause wet indicator paper to change color or become more acidic. This can be detected by a change in color on the indicator paper, indicating the presence of fluorine gas.
What colour does hydrogen turn moist universal indicator paper?
the formale name for it is scarlet but it means bright red
What is the effect of carbon monoxide on moist litmus paper?
Carbon monoxide does not have a direct effect on moist litmus paper as it is not an acidic or basic gas. Litmus paper changes color in response to acidic or basic substances.
What effect does hydrochloric acid have on universal indicator paper?
Hydrochloric acid will typically turn universal indicator paper red, indicating a low pH or acidity. Universal indicator paper changes color based on the pH of the solution it comes into contact with, with red indicating a strong acid.
Indicator made from lichens?
The indicator is litmus paper. :)
