Antimony Assay & Determination by Roasting Stibnite

The product obtained by roasting stibnite is likely to contain some unoxidized antimony trisulphide and a mixture of antimony trioxide and antimony tetroxide. It was desired to determine, as accurately as possible, the condition of the antimony as well as the total quantity present. Attempts were made to separate the trisulphide and the two oxides by methods based upon their varying ...

Flame Test Colors: Photo Gallery - ThoughtCo

 · The flame test is a fun and useful analytical technique to help you identify the chemical composition of a sample based on the way it changes the color of a flame. However, interpreting your results can be tricky if you don't have a reference. There are many shades of green, red, and blue, usually described with color names you wouldn't find on even a large crayon box.
