Does potassium nitrate create smoke?
You can make a smoke bomb using just the 3:2 ratio of potassium nitrate to sugar or a 5:3 ratio of potassium nitrate to sugar (e.g., 1-1/2 cups potassium nitrate and 1 cup sugar). Increasing the sugar helps the smoke bomb burn more slowly and produce smoke, but makes it harder to light.
Can smoke bombs cause a fire?
Although modern smoke grenades are designed not to directly emit fire or sparks, they remain a fire hazard and are capable of igniting dry vegetation or flammable substances if used injudiciously.
Why does potassium nitrate and sugar create smoke?
That is the reaction that is commonly found in sparklers, a combination of potassium nitrate, sugar, and metal filings. The reaction of sugar and nitrate makes heat, and the heat excites the metal filings, causing them to be oxidized and emit light. It is also the principal reaction in sugar rocket fuel.
What does KNO3 react with?
Molten potassium nitrate will react with carbon dioxide and water vapors to form potassium carbonate and hydroxide. Potassium nitrate will react with hydrochloric acid to release nitric acid, that will give off nitrogen dioxide fumes: 2 KNO3 + 2 HCl + H2O → 2 KCl + HNO3 + NO2 + H2O.
What color does potassium nitrate burn?
|Chemical Compound||Chemical Formula||Flame Color|
|Potassium Nitrate||KNO3||Light Purple|
|Copper II Chloride||CuCl2||Bluish-green|
What happens when you burn potassium nitrate?
Once heated, the potassium nitrate will produce enough oxygen for the reducing agent to react. Increase heat until a reaction takes place. The flame should burn a purple or lilac color due to the presence of potassium.
