Aluminium sulfate is a salt with the formula Al 2 (SO 4) 3.It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water [3] [4] and wastewater treatment plants, and also in paper manufacturing.
* may be tarnished in moist air or corrode in an acidic solution containing oxygen and an oxidant † attacked by sulfur or hydrogen sulfide § self-attacked by radiation-generated ozone. A noble metal is ordinarily regarded as a metallic element that is generally resistant to corrosion and is usually found in nature in its raw form.
The electricity is generated in such a way that, during discharge, metal atoms are released form the sodium moving to the positive electrode through the electrolyte. The electrolyte consists of a beta-alumina tube. Due to the fast and efficient ion transportation, β-alumina allows the battery to function at these high speeds and efficiency.
