your unknown solution made methyl red turn yellow. it also made phenolphthalein stay clear. what rang of pH does your unknown solution have?
phenolphthalein
One would add phenolphthalein as an indicator for bases with a pH of 8.2 to 10.0 If the phenolphthalein changes color from colorless to pink or red, a base with a pH between the aforementioned pH values is present.
It will turn purple
See the Related Link for instructions.
No, acids do
Add an acid.
Because Hydrochloric acid is an acid, phenolphthalein would be clear. In bases Phenolphtlalein becomes pink

It should be clear. Phenolphthalein doesn't change color in the presence of an acid, only a base.
As ammonia solution is alkaline, about pH 11 - 12, the phenolphthalein will turn pink.
yes
Phenolphthalein dissolves in water to get a clear transparent solution.
Acids and bases.
For solutions with a pH higher than 8.2, phenolphthalein turns bright pink.
Fdf
The Phenophtalein will remain clear.
