Pyridine is a colorless liquid. It boils at 115 degrees Celsius (239 F) and freezes at -42 degrees Celsius (-43.6 F). Its density is very close to that of water, at 0.982 gcm3 (water's density is 1). It is able to mix easily with water and most other organic solvents.
Sodium perchlorate is the inorganic compound with the chemical formula NaClO4. It is a white crystalline, hygroscopic solid that is highly soluble in water and in alcohol. It usually encountered as the monohydrate. The compound is noteworthy as the most soluble of the common perchlorate salts. Sodium perchlorate is the precursor to many other perchlorate salts, often taking advantage of their low solubility relative to NaClO4 (209 g100 mL at 25 °C). Perchloric acid is made by treating NaClO4 with HCl. Ammonium and potassium perchlorate, of interest in pyrotechnics, are prepared by double decomposition from a solution of sodium perchlorate and potassium or ammonium chlorides.
