Which equation describes the most suitable reaction for making lead sulphate?
A Pb + H2SO4 → PbSO4 + H2
B PbCO3 + H2SO4 → PbSO4 + CO2 + H2O
C Pb(NO3)2 + H2SO4 → PbSO4 + 2HNO3
D Pb(OH)2 + H2SO4 → PbSO4 + 2H2O
ms says its C buh why not D??:confused:

lead sulphate is an insoluble salt
so it has to be prepared by ionic precipitation of soluble salts
in D Lead hydroxide is insoluble(only Group 1 and 2 Metal Hydroxides are soluble)

Reactivity series !
Please (K) send (Na) cats (Ca) monkeys (Mg) and (Al) Zebras (Zn) In (Fe) large (Pb) huge (H) cage (Cu) . Make (Hg) sure(Ag) packed/padlocked (Pt)

Hope it helps, it did help me :) (y):cool::rolleyes:
Appreciated , but you are a bit too late brother!
4-5 Mnemonics have already been shared while Chemistry ATP was discussed!
P.S this one was included in that too!
