What is the difference between Ba(OH)2 and Ba(OH) 8H2O? From what I have found, they are both solids, but the Ba(OH) 8H2O contains water molecule, so why is it a solid?

Also may I know how to make an aqueous solution of barium hydroxide? What is the chemical formula for the aqueous barium hydroxide? This is for the process of transesterification of palm oil using alkali-based catalyst and methanol.

Answer #1

Ba(OH)2 and Ba(OH)2.8H2O both are crystalline solid. But Ba(OH)2 has 3D nerwork structure with Ba(II) cation and two hydroxide (OH-) ions. But later Has [Ba(H2O)8]^2+ complex ion and two hydroxide ions with Ba^2+ ion having co-ordination number of 8. , 29 H 2047 40 RR au oHo ou e o [Ba(H20)3724(er), or (Belowz Cordination No. 8. 81620) Because of strong ionic SATURDAY 30 in SUNDAY So formula for aqueus Bailmy is Ba?
