Lead nitrate and potassium bromide reaction?

Answer 1

Pb+K3ClO3 does not react because on the chemical activity series, Lead (Pb) is below Potassium (K) .

Added:

But Pb can reduce the chlorate ClO3- to give Cl- and 3 PbO, because Pb2+ (as oxide) is lower than chlorate in the reactivity scale of oxidants, the same as saying: Pb higher than Cl- as reductant.

3Pb(s) + ClO3-(aq) --> 3 PbO(s) + Cl-(aq)

(K+(aq) is tribened, not taking part in reaction, unchanged)

Remember that this is a heterogenous reaction (Liq./Sol.), taking place only at the inter-surface. This reaction will stop when all (free) Pb-metal surface is covered by lead oxide deposited on that. Then there is no contact for chlorate ions to the free Pb-surface.

Answer 2

Potassium chromate plus lead plus chloride in a balanced equation is given as .Pb(NO3)2 (aq) + K2CrO4 (aq) >> PbCrO4(s) + 2 KNO3 (aq)

The products are lead chromate and potassium nitrate.

Answer 3

Pb(NO3)2 (aq) + 2KCl (aq) --> 2KNO3 (aq)+ PbCl2 (s)

Answer 4

Pb(NO3)2 + K2CrO4 ------> PbCrO4 + 2KNO3

Answer 5

The balanced equation for potassium chromate and lead (II) acetate is as follows: Pb(CH3COO)2 (aq) + K2CrO4 (aq) ----> PbCrO4(s) + 2K+ (aq) + 2(CH3COO-) (aq)

Answer 6

Pb(NO3)2 + 2 KBr = PbBr2 + 2 KNO3

The lead bromide has a low solubility in water.

Answer 7

Pb + K2Cr2O7 ---> PbCr2O7 + 2K

Answer 8

K2CrO4
