For our experimental conditions today, we can assume that hydrogen gas adheres to the ideal gas law. Today's experiment is an example of a single replacement reaction. It involves the measurement of the volume of hydrogen gas generated from a reaction of zinc with excess hydrochloric acid. Zn (s) + 2HCl (aq) → ZnCl 2 (aq) + H 2 …

Typical methods for the treatment of waste pickling solutions include precipitation by alkaline reagents, most commonly calcium hydroxide. As a result, large volumes of galvanic sludge form, containing iron, calcium, sulphates, and a relatively small quantity of zinc (<20%), making Zn recovery not profitable. In summary, state-of-the-art …

The RLE process is the conventional zinc hydrometallurgy technology. It is generally composed of five major steps, i.e., roasting, leaching, solution purification, electrowinning, and casting. As shown in Fig. 1.2, the existing form of zinc experiences complex transitions from complex zinc ore to pure zinc metal.

burner and the heating effect of the electric current. If the zinc chloride does begin to boil then it could boil over the sides of the crucible. Boiling also produces fumes of zinc chloride in the air, which rapidly solidify to form a fine powder. The bubbles of zinc chloride fumes could be confused with those of the chlorine gas being formed.
