What precipitate is formed from sodium chloride and lead nitrate?

Answer 1

2NaCl + Pb(NO3)2 ---H2O--> 2Na(NO3) + PbCl2

Double displacement rxn, Na replaces Pb because its higher on the activity series table. The product is NaNO3 which is dispersed through the solvent as free ions and PbCl2 is the precipitate because it is insoluble.

Answer 2

Strontium sulfate. You have 4 ions here... Two cations: H+ and Sr2+ Two anions: NO3- and SO42- To form an insoluble compound, you need to create a REALLY stable ionic compound, which means hooking together some combination of cation and anion that is stable enough together that they would not want to be apart and interacting with lots of polar water molecules. So let's look at the possibilities: HNO3 -- Can't possibly be insoluble for two reasons: (1) HNO3 is a covalent compound out of water---a gas at room temperature, not a solid. You don't get insoluble solids from compounds with hydrogen as a cation because they are not ionic. (2) Nitrate is soluble with EVERYTHING. It is perhaps the most soluble anion out there. So it will never form an insoluble solid. SrSO4 -- So by process of elimination this has to be it. Sulfate compounds are often soluble, but forms insoluble (or partially insoluble) compounds with all of the alkaline earth metals starting with Calcium and going down.

Answer 3

Sulfuric acid reacts with most metals via a single displacement reaction to produce hydrogen gas and the metal sulfate. Dilute H2SO4 attacks iron, aluminium, zinc, manganese, magnesium and nickel, but reactions with tin and copper require the acid to be hot and concentrated. Lead and tungsten, however, are resistant to sulfuric acid. The reaction with iron (shown) is typical for most of these metals, but the reaction with tin is unusual in that it produces sulfur dioxide rather than hydrogen.Fe(s) + H2SO4(aq) → H2(g) + FeSO4(aq)Sn(s) + 2 H2SO4(aq) → SnSO4(aq) + 2 H2O(l) + SO2(g)

So no reaction takes place between lead and Sulfuric acid. The equation would be as follows: Pb (s) + H2SO4 (aq) = Pb (s) + H2SO4 (aq)

Answer 4

Pb(NO3)2 (aq) + H2SO4 (aq)=> PbSO4(s) + 2HNO3 (aq)

Pb2+(aq)+2NO3-(aq)+2H+(aq)+SO4-(aq) => PbSO4(s)+2H+(aq)+2NO3-(aq)

Pb2+(aq)+SO4-(aq)=>PbSO4(s)

Answer 5

Pb2+ + 2 Cl- ↔ PbCl2↓

The precipitation is incomplete and strongly depending on elemental concentrations and solvent temperature.

Answer 6

The reaction is:

Na2CO3 + Pb(NO3)2 = PbCO3 + 2NaNO3

The lead carbonate is a white precipitate.

Answer 7

lead nitrate + copper sulphate --> lead sulphate + copper nitrate

Pb(NO3)2 + CuSO4 --> PbSO4 + Cu(NO3)2

Answer 8

The molecular equation is Pb(NO3)2 + H2SO4 => PbSO4 + 2 HNO3.

Answer 9

Pb2+(aq) + SO42-(aq) --> PbSO4(s) , because the other salt NaNO3 is soluble.

Answer 10

lead sulfate
