Does nano3 turns phenolpthalein indicator pink?
nono3 is a base, not acid.
It should turn the phenolpthalein pink if the Ph is over about 8
whoops, Dr Bob is right, Ph is neutral ,about 7.
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.
To determine whether NaNO3 (sodium nitrate) turns phenolphthalein indicator pink or not, we need to understand the properties of both substances and their interaction.
Phenolphthalein is an acidic-base indicator that is typically colorless in acidic solutions and turns pink or magenta in alkaline (basic) solutions.
Sodium nitrate (NaNO3) is a salt that dissociates into sodium ions (Na+) and nitrate ions (NO3-) in water. It is a neutral substance and does not have any significant effect on the acidity or basicity of a solution.
Since sodium nitrate does not have any alkaline or basic properties and does not significantly change the pH of a solution, it would not cause phenolphthalein to turn pink.
In general, phenolphthalein turns pink in the presence of strong bases such as hydroxides (OH-) or carbonates (CO3^2-). If you have a solution and want to test whether it is alkaline or acidic using phenolphthalein, you can add a few drops of the indicator to the solution and observe any color change. If it turns pink, it indicates that the solution is alkaline or basic. If it remains colorless, the solution is either neutral or acidic.
