<span>1. MgBr2

Soluble.

Rule: all the binary compounds of the group 17 (different to F) with metals are solubles, except those formed with Ag, Hg (I) and Pb.

2. PbI2

Insoluble.

Rule: it is one of the exceptions stated in the rule above.

3. (NH4)2CO3

Soluble.

Rule: salts containing NH4(+) are soluble.

4. ZnSO4

Soluble

Rule: </span><span>This salt is not an exception to the rule that most sulfate salts are soluble. Important exceptions to this rule include BaSO4, PbSO4, Ag2SO4 and SrSO4

5. Sr(OH)2

Soluble (slightly soluble).

Rule: </span><span>Hydroxide salts of Group II elements (Ca, Sr, and Ba) are slightly soluble</span>

MgBr2 is soluble in water; lead iodide (PbI2) is soluble in hot water, (NH4)2CO3 is soluble in water, anhydrous ZnSO4 is soluble in water.

Further explanation:

MgBr2

MgBr2 is a chemical compound which is soluble in water. Its solubility is 102g/100mL in water. It is also soluble in ethanol or methanol, Sr(OH)2 is soluble in cold water slowly.  

Lead iodide (PbI2)

Lead iodide (PbI2) is a salt. It is insoluble in cold water and it has more density as compare to water. Its solubility increases with an increase in temperature. While it is not soluble in ethanol and HCl(cold).

Ammonium carbonate (NH4)2CO3

It is salt which is readily converted to gaseous ammonia and CO2 on heating. It is soluble in water but decomposes in hot water.  

Zinc Sulfate ZnSO4

Zinc sulfate in form of hexahydrate, ZnSO4.6H2O, and heptahydrate ZnSO4.7H2O are soluble in water. Its solubility is 57.7g/100g at room temperature. Its solubility increases with an increase in the temperature. It is also not soluble in ethanol.  

Strontium hydroxide Sr(OH)2

It is an alkali. It is slightly soluble in cold water. It is also soluble in acid. It is not soluble in acetone. With an increase in temperature its solubility also increases in water.

Consider a generic redox reaction?
vesna_86 [32]
The Nernst equation allows us to predict the cell potential for voltaic cells under conditions other than the standard conditions of 1M, 1 atm, 25°C. The effects of different temperatures and concentrations may be tracked in terms of the Gibbs energy change ΔG. This free energy change depends upon the temperature & concentrations according to   ΔG = ΔG°  +  RTInQ  where ΔG° is the free energy change under conditions and Q is the thermodynamic reaction quotient. The free energy change is related to the cell potential  Ecell by ΔG= nFEcell

so for non-standard conditions
              -nFEcell = -nFE°cell  + RT InQ

or
   
              Ecell  =  E°cell - RT/nF (InQ) 

which is called Nernst equation.
