Does nano3 turns phenolpthalein indicator pink?

Answer 1

No

Answer 2

nono3 is a base, not acid.
It should turn the phenolpthalein pink if the Ph is over about 8

Answer 3

whoops, Dr Bob is right, Ph is neutral ,about 7.

Answer 4

Yes, NaNO3 is the salt of a strong base (NaOH) and a strong acid (HNO3) which makes it a neutral salt with a pH of very near 7.0 (temperature and activity etc) and phenolthalein doesn't change to pink until well above 7.
