no, acids do
your unknown solution made methyl red turn yellow. it also made phenolphthalein stay clear. what rang of pH does your unknown solution have?
It should be clear. Phenolphthalein doesn't change color in the presence of an acid, only a base.
yes
Phenolphthalein dissolves in water to get a clear transparent solution.
The Phenophtalein will remain clear.
Fdf
Pink
No, acids do
phenolphthalein is a weak acid, when reacting with strong alkali it turns pink
Nothing will happen... but when you put a drop of the vial in the phenolphthalein, the phenolphthalein will turn into pink... It was just an observation that I saw in our experiment this afternoon
Because Hydrochloric acid is an acid, phenolphthalein would be clear. In bases Phenolphtlalein becomes pink
