Answer: Pb (lead) is above hydrogen in reactivity series. A reaction with dilute hydrochloric acid gives a metal chloride and hydrogen. D They turn blue litmus paper red. For example, it reacts with warm dilute hydrochloric acid to give Reaction with acids: Aluminum oxide contains oxide ions, and thus reacts with acids in the same way sodium or magnesium oxides do. Method. It is dangerous to put these metals into an acid. It reacts slowly with dil. 18 Concentrated aqueous sodium chloride, concentrated hydrochloric acid and molten lead bromide were separately electrolysed in experiments 1, 2 and 3. platinum electrodes concentrated aqueous sodium chloride experiment 1 experiment 3 platinum electrodes concentrated hydrochloric acid experiment 2 d.c. power supply lamp LEAD BROMIDE TOXIC heat As with the reactions with water, there are odd cases where the reactivity isn't quite what you would expect.
