An excess of sulfuric acid is added to potassium nitrate, and more or less pure nitric acid is distilled away from the resulting potassium sulfate. Careful temperature control is important ...

So, if astrobiologists ever do find alien life with a weird chemistry that uses some liquid other than water, it's not likely ...

FOR the analysis of the nitrate content of sea water, and for certain tests on alkaloids, it is necessary to have sulphuric acid free from all but the most minute amounts of nitric acid.

Strong acids such as hydrochloric acid, sulfuric acid and nitric acid are laboratory acids that have been mixed with a lot of water before putting them out for use. This is called diluting the acid.

Another important aspect of dissolution kinetics is the behavior of thorium silicate in sulfuric acid, which, while not directly related to nitric acid, provides insights into the dissolution ...

The first step is to react the copper nitrate with sulfuric acid, which results in nitric acid and copper sulfate. From there, the copper sulfate is placed in an electrolysis cell using a platinum ...

Three bottles of sulfuric acid, acetone and a "white substance labeled potassium nitrate" can be seen in one of the documents, which also mention a "burner with white residue," a thermometer ...

Dilution with water produces heat. When diluting, always add acid slowly to water (do not add water to acid). Nitric acid is a powerful oxidizing agent and can react explosively with most organic ...
