As a consequence of its structure where there are no significant lattice forces, gallium trichloride has the lowest melting point of all of the aluminium, gallium and indium trihalides. The formula of Ga 2 Cl 6 is often written as Ga 2 (Î¼-Cl) 2 Cl 4.
69 DETERMINING IONIC FORMULASsodium sulfate strontium oxidebarium hydroxidechromium(III) nitratetitanium(IV) chloridetin(II) phosphate Don't forget the parenthesis when you havemore than one hydroxide ion! 70 HYDRATES-many ionic compounds are formed by crystallizing the compound from water. Sometimes, this causes water molecules to become part of the crystal structure. - This water is present in a definite ratio to the ions in the compound. Can be removed by heating, butwill NOT evaporate if the compound is left standing. dot indicates that the water is weakly bound to the ionic compound # water molecules per formula unit of compound-many DESSICANTS are hydrates that have had their water molecules driven off.
