An inorganic substance with the formula BaCl2 is barium chloride. It is one of the most popular barium salts that dissolve in water. Like the majority of other water-soluble barium salts, it is white, extremely hazardous, and gives flames a yellow-green tint.
When 1 mole of bacl2 is dissolved in water it releases-8.67 kj/mil of energy. calculate h when 10.3 g of barium chloride is dissolved to make a 1.00 l solution
In water, barium chloride is very soluble (as is the case with most ionic salts). In its dissolved condition, it is known to split into barium cations and chloride anions.
Let's first determine the total amount of CL- ions.
=> When HCl dissociates, one mol will produce H+ and one mol will produce CL-. Thus, . 2 moles yields. 2 mol CL-
=> One mole of Bacl2 will dissociate into one mole of Ba2+ and two moles of CL-. Therefore, 0.1 mol will result. two moles CL-
Hence, there are mols of CL- in total.
2+.2 = .4
=> Molarity:
Total moles of solute divided by liters of solution gives the molarity, M.
= .4/.5 = 0.8 M
As a result, 0.8 M is the molarity of CL- in solution.
