No
Answered by Damon
nono3 is a base, not acid.
It should turn the phenolpthalein pink if the Ph is over about 8
Answered by Damon
whoops, Dr Bob is right, Ph is neutral ,about 7.
Answered by DrBob222
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.
