Sodium perchlorate is the precursor to ammonium, potassium and lithium perchlorate salts, often taking advantage of their low solubility in water relative to NaClO 4 (209 g/(100 mL) at 25 °C). [6] It is used for denaturating proteins in biochemistry and in standard DNA extraction and hybridization reactions in molecular biology.
Units of solubility are given in grams of substance per 100 millilitres ... Ammonium carbonate monohydrate (NH 4) 2 CO 3 ·H 2 O: 55.8: ... Sodium perchlorate: NaClO ...
The gram-atom is a former term for a mole of atoms, and gram-molecule for a mole of molecules. [7] Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass (M r). [8]
Perchlorate salts are typically manufactured through the process of electrolysis, which involves oxidizing aqueous solutions of corresponding chlorates.This technique is commonly employed in the production of sodium perchlorate, which finds widespread use as a key ingredient in rocket fuel. [5]
It is a powerful oxidizer when hot, but aqueous solutions up to approximately 70% by weight at room temperature are generally safe, only showing strong acid features and no oxidizing properties. Perchloric acid is useful for preparing perchlorate salts, especially ammonium perchlorate, an important rocket fuel component. Perchloric acid is ...
Sodium chlorate is toxic: "doses of a few grams of chlorate are lethal". [7] (ld50 oral in rats 1200mg/kg) The oxidative effect on hemoglobin leads to methaemoglobin formation, which is followed by denaturation of the globin protein and a cross-linking of erythrocyte membrane proteins with resultant damage to the membrane enzymes.
Lithium perchlorate is also used as an electrolyte salt in lithium-ion batteries.Lithium perchlorate is chosen over alternative salts such as lithium hexafluorophosphate or lithium tetrafluoroborate when its superior electrical impedance, conductivity, hygroscopicity, and anodic stability properties are of importance to the specific application. [11]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
