Garnet - Wikipedia

Andradite is a calcium-iron garnet, Ca 3 Fe 2 (SiO 4) 3, is of variable composition and may be red, yellow, brown, green or black. The recognized varieties are demantoid (green), melanite (black), and topazolite (yellow or green). Andradite is found in skarns and in deep-seated igneous rocks like syenite as well as serpentines and greenschists.

Drying agents

Mar 21, 2016· Calcium chloride (n=6, e=1.5 mg/L) is a very good drying agent for a broad variety of solvents but is generally not compatible with hydroxy (alcohol, phenol), amino (amine, amide) and carbonyl (acid, ketone, ester) functions due to basic impurities such as Ca(OH) 2 and CaCl(OH). In addition, it tends to form adducts with some of those compounds

Drying agents

Mar 21, 2016· Calcium sulfate (n=0.5, e=0.004 mg/L) is a neutral and good drying agent. However, it does not have a high capacity, which makes it useless for very wet solutions. The commercially available Drierite® contains about 2 % cobalt chloride as indior, which can be leached out into various solvents i.e. ethanol, DMSO, DMF, ethers, etc. Drierite is often used in desicors .

Characteristics of Water - Physical, Chemical and Biological

pH + pOH = 14 if the pH of water is more than 7, it will be alkaline and if it is less than 7, it will be acidic. The alkalinity is caused by the presence of bicarbonate of calcium and magnesium or by the carbonates of hydroxides of sodium, potassium, calcium and magnesium. Some, but not all of the compounds that cause alkalinity also cause hardness.

WebElements Periodic Table » Calcium » the essentials

Stalagmites and stalactites contain calcium carbonate (CaCO 3). Calcium carbonate is the basis of the cement industry. Calcium is classified chemically as one of the alkaline earth elements (that is, in Group 2 of the periodic table. The metal is rather reactive. It readily forms a white coating of calcium nitride (Ca 3 N 2) in air. It reacts with water and the metal burns with a yellow-red flame, forming largely the nitride.
