Sodium Alum

Sodium Aluminum Sulfate. Sodium aluminum sulfate [7784-28-3], NaAl(SO 2 12H20, known as sodium alum, is a colorless crystal having an asttingent taste mp 61°C and sp gr 1.675. It is the most water soluble alum 75 g per 100 mL H2O at 20°C (8). It is soluble ia dilute acid and iasoluble ia alcohol. [Pg.177]

Sodium alum occurs naturally as the mineral mendo2ite. Commercially, it is produced by the addition of a sodium sulfate solution to aluminum sulfate. Small amounts of potassium sulfate, sodium siUcate, and soda ash can be added to improve product handling and performance. After adjustment of the ratio of aluminum sulfate to sodium sulfate, water is evaporated to give a hard cake ia the cooling pans. This cake is further heated ia roasters and ground to a fineness of 99% through a 100-mesh (- 150 fiva) sieve. [Pg.177]

When he heated the pulverized mineral with concentrated sulfuric acid, it dissolved with evolution of hydrofluoric acid. When he evaporated the solution without adding any alkali, he obtained octahedral crystals. Since sodium alum was not yet known to exist, he concluded that the cryolite must contain potassium (150). When the Brazilian scientist J. B. de Andrada e Sylva described this mineral in 1800, he too stated that it contained potassium (151). Klaproth s analysis in the same... [Pg.609]

In addition to the simple compounds, sodium forms double salts of various types, although because of the relatively small size of the Na+ 1011, die number of sodium alums (see also Alum) is relatively small. [Pg.1490]

Baking powder contains baking soda (NaHC03) and an acidic substance such as sodium alum, NaAl(S04)2 12 H20. These components react in an aqueous medium to produce C02 gas, which "raises" the dough. Write a balanced net ionic equation for the reaction. [Pg.660]
