Besides liquor sodii ethylatis the following salts and preparations are used in the British Pharmacopoeia.
(i) Sodii carbonis, known as washing soda; this carbonate on heating yields sodii carbonis exsiccatus and sodii bicarbonas; from the latter is made trochiscus sodii bicarbonatis.
(2) Sodii phosphas.
From sodium phosphate are made sodii phosphas effervescens and sodii hypophosphis (see Phosphorus).
(3) Sodii sulphas (Glauber's salt), with its sub-preparation sodii sulphas effervescens.
(5) Sodii citro-tartras effervescens, a mixture of sugar, sodium bicarbonate, citric and tartaric acids.
(6) Sodii chloridum, common salt.- (7) Sodii sulphas.
For sodii bromidum, iodidum and salicylatum see Bromine, Iodine and Salicylic Acid respectively.
For sodii arsenas and cacodylate see Arsenic. Sapo durus (hard soap) is a compound of sodium with olive oil, and sago animalis (curd soap) is chiefly sodium stearate.
The liquor sodii ethylatis is a powerful caustic and is used to destroy small naevi and warts.
