### colorless solid:

Potassium nitrate
* Some potassium nitrate causes gastroenteritis.
* common nitrate.
* is believed to prevent the protein from denaturing in the acidic milieu
  - inorganic compounds
  - ionic compounds
  - one of the safer sources of potassium
  - the main explosive ingredient in gunpowder
  - toxic substances
* is used in explosives
  - producing matches and explosives
* little toxic.
* needs to be very hot before it melts.
* primary ingredient of fireworks.
* strong oxidizer.
* very rich source of oxygen.
+ Nitrate: Nitrogen compounds
  * It is a strong oxidizing agent. It is found in the earth in some very dry places. Potassium nitrate is a common nitrate. Nitrites are similar.
+ Potassium nitrate, Properties: Potassium compounds :: Nitrogen compounds
  * Potassium nitrate is a colorless solid. It dissolves in water. It is a common source of the nitrate ion. Potassium nitrate is a strong oxidizer. It decomposes to potassium nitrite and oxygen when heated. Its pH is almost neutral.
  * Potassium nitrate is a colorless solid. It dissolves in water. It is a common source of the nitrate ion. Potassium nitrate is a strong oxidizer. It decomposes to potassium nitrite and oxygen when heated. Its pH is almost neutral. It burns with a lilac flame
  - Safety
  * Potassium nitrate is a little toxic. It also can start fires easily
  * Potassium nitrate is used in explosives. Oxygen from the air is the most common chemical that is used for oxidation, which is how most fires and explosions happen. Some explosions will use up oxygen so quickly, though, that there is not enough to finish the reaction, and the explosion is not very strong. Potassium nitrate replaces the need for oxygen and takes up much less space, which lets the explosion be stronger and faster. It is a main ingredient of gunpowder
+ Rocket candy, Preparation: Fuel :: Rockets
  * First, the potassium nitrate is ground or milled. It needs to be made into a powder. Then the potassium nitrate is mixed with powdered sugar in a pot. When the heat is turned on, the sugar melts. However, this method does not actually melt the potassium nitrate. Potassium nitrate needs to be very hot before it melts. Its melting temperature is 613 degrees Fahrenheit. So instead of melting, the grains of potassium nitrate are coated with the melted sugar.

### colorless solid:

Sodium chlorite
* are chemical compounds.
* is also the trigger for the release of chlorine dioxide
  - made into chlorine dioxide for infectious disease control
  - the most common chlorite
* reacts with hydrochloric acid to make chlorine dioxide.
+ Chlorine dioxide, How it is made: Chlorine compounds :: Oxides
+ Chlorite: Chlorine compounds
  * It is an oxidizing agent. They can be known as salts of chlorous acid. Some chlorites are explosives. It can be made by dissolving chlorine dioxide in a base. It can also be made by reduction of chlorate with hydrogen peroxide. Sodium chlorite is the most common chlorite.
+ Sodium chlorite, Properties: Sodium compounds :: Chlorine compounds
  * Sodium chlorite is a colorless solid. It is a powerful oxidizing agent. It disproportionates sometimes. It forms the unstable chlorous acid when reacted with a strong acid.
