Will anyone guide me to internet sites for highly technical exchange of views regarding chemical technology;material handling;inorganic chemistry, finding books on inorganic chemistry?

This phenomenon is known as invert solubility and to the best of my knowledge is applicable to CaSO4 and not Ca(OH)2 ; which is partially soluble in water

pH value is actually -log{H} . i.e. negative log of hydrogen ion concentration in water. pH value of 0 and 14 can never be achieved because at pH 0 solutionwill contain only Hydrogen ions and @ pH 14 it will contain only -OH ions.

put some strongly hygroscopic powder which is free of moisture in the descicator and keep KNO3 in a dish.close the lid and KNO3 should be dried shortly. But DO NOT HEAT IT

Thank you. But I was looking to precipitate Dicalcium Phosphate without 2 moles of hydration at room temperature

Can anyone help in suggesting method to manufacture Dicalcium Phosphate Anhydrous CaHPO4 [Mol.Wt.136] with no water of hydration from Commercial Grade Phosphoric Acid at Standard Temperature and Pressure?
