An ion of lead is represented by $^{207}_{82}\text{Pb}^{2+}$. Deduce the number of electrons and neutrons in this ion.
Lead(IV) oxide, $\text{PbO}_2$, is an oxidising agent. Describe a test used for oxidising agents. test ……… observations ………
When lead(IV) oxide reacts with concentrated hydrochloric acid, the products are lead(IV) chloride, $\text{PbCl}_4$, and water. Construct the equation for this reaction.
When lead(IV) chloride is warmed in a closed container an equilibrium mixture is established. $\text{PbCl}_4(\ell) \rightleftharpoons \text{PbCl}_2(\text{s}) + \text{Cl}_2(\text{g})$ Describe and explain the effect, if any, on the position of equilibrium when the concentration of chlorine is increased.
Describe and explain the effect, if any, on the position of equilibrium when the temperature is raised.
Name a lead salt which dissolves in water.
