I want to know about the reaction of Sodium Acetate or Sodium formate with Nitric acid.
Is this reaction (C2H3NaO2 + HNO3 = NaNO3 + C2H4O2) is possible in boiling nitric acid?
Dear Siavash,
Yes it is possible, however, you should use an excess of nitric acid. For better yields you can remove the formic acid or acetic acid formed during the course of the reaction by distillation since this important step forces the reaction to go to completion. Otherwise, the reaction will be at equilibrium and some of the sodium formate or acetate will be remained unreacted.
Hoping this will be helpful,
Rafik

Hi, with boiling concentrated nitric acid you will oxidise acetic or formic acid, and also produce organic nitrates. Use 50% sulphuric or phosphoric acid to avoid such degradation.
You have a very high chance to create an EXPLOSIVE mixture by mixing whatever organic material with a concentrated nitric acid. Before carrying out whatever chemical reaction, first think about safety!
I'm just curious why my evident comments were downvoted? Please, explain what was wrong.
@Yurii V Geletii, @Peter Kapusta, @Rémi Losno.
I have a solution that contains sodium hydroxide and formic acid and i want to destroy formate from medium. What can i do?
Formic acid may be discharged to the sewer in concentrations of approximately one percent or less. Check pH, adjust to about neutral, dilute it with water to less than 1 % of formic acid and discharge it to the sewer.
The selective removal of formate from a reaction solution is a real challenge and would be extremely difficult.

I have a solution that contains lanthanum. and i want to determine to concentration of lanthanum in solution with titration. this solution contains formate.
I used hexamine as buffering agent and xylenol orange as indicator and i did titration at pH=5.5 but formate or acetate was interfere. to destroy Formate or acetate, i added HNO3 in my solution and boil to evaporate all of solution and next dissolve the residues in water and i did titration.
Now, i don't know that this method is correct or not?
This my comment was also downvoted "I'm just curious why my evident comments were downvoted? Please, explain what was wrong." The comments of Peter Kapusta were also downvoted. This is not the right way in discussions. Instead of downvoting you have to provide arguments why you disagree. I downvoted the comments of Rafik Karaman and explained why.
@Yurii V Geletii
Dear Yurii V Geletii;
My question was about destroying formate or acetate from a aqueous solution.I upvoted all of your comments. but about comments of Peter Kapusta, in your opinion, comments of Peter Kapusta are my question's answer?
"Have you ever seen concentrated nitric acid in action? Apparently not, because otherwise you would not upvote the wrong double answer of Rafik Karaman. I wouldn't like to be your labmate."!!!
Siavash,
I meant this Peter's comment: " @ Siavash Jahanrad:
These are completely different questions, problems. Different from the original one, what we have tried to answer. You have also changed the phrasing of the original question."
I do not see anything wrong in this statement. It's not worth to be downvoted.
Concerning "Have you ever seen concentrated nitric acid in action?" I've seen it, therefore I advised you in my first comment to think about safety. While Peter's wording was too straightforward, it helped to capture your attention to the safety. In a very urgent case, we must act in whatever way to prevent a disaster. In your original question you were asking about CONCENTRATED nitric acid.
