Hydrochloric acid reacts with zinc, giving zinc chloride and hydrogen.Also,hydrochloric acid in concentrated aqueous solution undergoes electrolysis (with electrodes inert).
Define:
a) the mass in grams of the product in the cathode, if there are 0.5 mol/100 ml of HCl in the solution;
b) boiling under normal conditions of the gas obtained in the anode, if the pH of the acid is 2;
c) the mass in grams of the metal obtained in the cathode (electrolyzed glass), if the salt of zinc is formed by the interaction of 3.65 g of hydrochloric acid with zinc.
