Flame test. Dip a piece of platinum wire into concentrated nitric acid, and then roll it in the sample. Put the wire over a Bunsen flame. If a lilac flame is observed, it is potassium nitrate.

Is ammonium nitrate fertilize considered a cmemical?

Ammonium nitrate is a chemical. It is not only used as a fertilizer but also as an explosive. If you drive past an open pit mine at a little before 3 pm, you will see traffic stopped. Get out of your car. Walk over to the observation area. Watch the explosion. The chemical used is ammonium nitrate.


What chemical is burning when you see a violet purple flame?

When you see a violet-purple flame, it often indicates the presence of potassium compounds, such as potassium chloride or potassium nitrate. The specific element responsible for the color is potassium.

No, from the safety data sheets it contains diquat dibromide. See link for chmistry.


What is the Ka value for ammonium nitrate?

The pKa of ammonium nitrate (NH4NO3) is approximately 4.1. This is a weak acid. Split it apart into NH4 and NO3. Add OH to NH4 and H+ to N03. NH40H is a weak base, while HNO3 is a strong acid. Strong acid + weak base =H= weak acid. You could also just look at the pKa value, convert it into Ka, and see that it is more acidic. To convert, do 10^-pKa. You should get 7.9 x 10^-5. This value shows it is acidic.

When solutions of silver nitrate and potassium bromide are mixed what do you see?

The reaction is:AgNO3 + KBr = AgBr = KNO3Silver bromide is a precipitate.


What is a brown ring test for analysis of nitrate anion?

The brown ring test is a qualitative test used to detect the presence of the nitrate anion. In the test, a sample containing nitrate ions is treated with freshly prepared iron(II) sulfate solution and concentrated sulfuric acid. A brown ring at the junction of the two layers forms if nitrate ions are present.


How can you separate potassium chloride and ammonium chloride?

A mixture of ammonium chloride and potassium chloride can be separated using the process of sublimation. You must also note that both these substances are sublimable. So, the question arises that how can these substances be separated using this technique? This technique is quite feasible in this case as the sublimable temperatures of ammonium and potassium chloride differ widely. Between the two, ammonium chloride (See the related link) has lower sublimable temperatures. Therefore, it sublimes first followed by potassium chloride.


What volume of nitrous oxide can be produced from the decomposition of 0.55 moles of ammonium nitrate?

Using the balanced chemical equation for the decomposition of ammonium nitrate, 2NH4NO3 --> 2N2O + O2 + 4H2O, we can see that 2 moles of nitrous oxide (N2O) is produced for every 2 moles of ammonium nitrate (NH4NO3). Therefore, 0.55 moles of NH4NO3 will produce 0.55 moles of N2O. The volume of N2O can then be calculated using the ideal gas law equation (V = nRT/P) and given conditions.


How do you separate potassium nitrate from potassium oxide?

Yes. If you mix it with a metal that is higher on the Activity Series of Metals, that metal will replace the lower metal. In our case, Lithium is the only element that is higher than potassium. So, the Lithium would replace the Potassium, forming Potassium and Lithium Nitrate.
