It turns blue
Sodium hydroxide turns red litmus paper blue.
Sodium hydroxide is a strong base, so it will turn blue litmus paper to red. This color change is due to the alkaline nature of sodium hydroxide which reacts with the blue litmus paper to change its color.
dark green (but orange - brown if left standing)
They are not soluble, therefore they do not precipitate or form a color....a.k.a....no reaction...

NOTHING! Sodium hydroxide (NaOH) is a base, and BLP does not change color with a base.
Red litmus paper turns blue in sodium hydroxide because the red litmus paper is indicating the presence of acidity. When it comes into contact with sodium hydroxide, a strong base, the base neutralizes the acid on the litmus paper, causing the color change to blue.
no it does not
A litmus test is one way of comparing. Sodium Chloride is a neutral salt and so would have no effect on litmus. Sodium Hydroxide is a base, and would turn litmus blue.
yes, it turns in purple or a very light pink-ish purple color
Green
When a drop of sodium hydroxide (NaOH) is added to blue litmus paper, there will be no color change, as blue litmus paper is already indicative of a basic (alkaline) environment. Sodium hydroxide is a strong base, and blue litmus paper remains blue in the presence of bases. In contrast, if red litmus paper were used, it would turn blue, indicating the presence of a base.
acids turn blue litmus peeper to red
It is a waxy-white.
Methyl orange is yellow in dilute sodium hydroxide.
