The western desert of Egypt was a major source of alum substitutes in antiquity. These evaporites were mainly FeAl 2 (SO 4) 4 ·22 H 2 O, MgAl 2 (SO 4) 4 ·22 H 2 O, NaAl(SO 4) 2 ·6 H
Aluminium trichloride (AlCl 3) has a layered polymeric structure below its melting point of 192.4 °C (378 °F), but transforms on melting to Al 2 Cl 6 dimers with a concomitant increase in volume by 85% and a near-total loss of electrical conductivity
Potassium alum, potash alum, or potassium aluminium sulfate is a chemical compound first mentioned under various Sanskrit names in Ayurvedic medicinal texts such as charak samhita, sushrut samhita, and ashtang hridaya; is chemically defined as the double sulfate of potassium and aluminium, with chemical formula KAl(SO 4) 2.
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.
The deadliest shootings in Maine history stunned a state of 1.3 million people that has relatively little violent crime and had only 29 killings in all of 2022.
Ammonium aluminium sulfate, also known as ammonium alum or just alum (though there are many different substances also called "alum"), is a white crystalline double sulfate usually encountered as the dodecahydrate, formula (NH 4)Al(SO 4) 2 ·12H 2 O.
