The reaction of WCl_6with Al at about 400^@Cgives black crystals of a compound that contains only tungsten and chlorine. A sample of this compound, when reduced with hydrogen gives 0.2232 g of tungsten metal and hydrogen chloride, which is absorbed in water. Titration of the hydrochloric acid thus produced required 46.2 mL of 0.1051-M NaOH to reach the end point. What is the empirical formula of the black tungsten chloride?
