Which of the following solutions will give a precipitate with dilute tetraoxosulphate (V) acid? l. Lead (ll) trioxonitrate (V) solution ll. Barium chloride solution lll. Sodium chloride solution
l only
ll only
l and ll only
ll and lll only
Correct answer is C
Both i and ii will precipitate with H2SO4, SEE EQUATION BELOW
Pb(NO3)2+H2SO4→PbSO4+2HNO3.
H2SO4 +BaCl2 → BaSO4 + 2HCl
both PbSO4 and BaS04 are slightly solid so they precipitate out of solution as solid
