Brown algae (Phaeophyta) includes Kelps (Macrocystis, Laminaria) and Ascophyllum, Fucus, and Sargassum. Alginic Acid (Alginate) is a colloidal product used for thickening, suspending, stabilizing, emulsifying, gel-forming, or film-forming, as required. 1  About half of the alginate produced is used for making ice cream and other dairy products, the rest is used in other products, including shaving cream, rubber, or paint.
Lithium is a Group 1 (IA) element containing just a single valence electron (1s 2 2s 1). Group 1 elements are called alkali metals. Lithium is a solid only about half as dense as water and lithium metal is the least dense metal. A freshly cut chunk of lithium is silvery, but tarnishes in a minute or so in air to give a grey surface. Its chemistry is dominated by its tendency to lose an electron to form Li + .
Lithium, the third element in the periodic table, is a soft, silvery-white alkali metal. It is the lightest of all metals. As a whole, the Earth's crust contains approximately 20 parts per million of lithium, and the oceans contain 0.17 parts per million; the atmosphere contains only trace amounts. [1]. Lithium has many industrial uses. It goes into glasses, ceramics, pharmaceuticals, and aluminum and magnesium alloys.
