calcium hydroxide turn red litmus paper into blue because it is a base. it does not have any effect on blue litmus paper.
HOW DOES IT CHANGE
Calcium hydroxide is basic and hence the litmus will remain blue.
It will turn blue because hydroxides are alkaline
Blue litmus paper turns red in an acid and remains blue in a base such as sodium hydroxide. Red litmus paper would turn blue in the base sodium hydroxide.
the red litmus paper turns blue and the blue litmus paper remains blue indicating that the mixture is acidic>
Ammonia solution consists of ammonium hydroxide and water, the ammonium hydroxide is basic (due to the hydroxyl functional group). Dry ammonia doesn't have this functional group.
Calcium hydroxide is basic and hence the litmus will remain blue.
red litmus paper becomes blue in its presnece
As any hydroxide being a strong base, it turn litmus paper blueRememberBase is Blue andaciD is reD
It will turn blue because hydroxides are alkaline
Blue litmus paper turns red in an acid and remains blue in a base such as sodium hydroxide. Red litmus paper would turn blue in the base sodium hydroxide.
as magnecium hydroxide is a base so it will turn red litmus blue...
Turns litmus paper blue
the red litmus paper turns blue and the blue litmus paper remains blue indicating that the mixture is acidic>
red
red litmus paper turns blue in sodium hydroxide
acids turn blue litmus peeper to red
With a pH of 12 it is very alkaline and would turn universal indicator dark blue.
