Consider the molar solubility of SrCO3 in 0.10 M Sr(NO3)2 versus in pure water. Ksp SrCO3 = 5.4 x 10-10 Which statement is true? A. The solubility of Sr(NO3)2 increases. B. The molar solubility of SrCO3 will be higher in 0.10 M 0 M Sr(NO3)2. C. The molar solubility of SrCO3 will be lower in water. D. The molar solubility of SrCO3 will be lower in 0.10 M 0 M Sr(NO3)2 because of Sr2+ E. There is not enough information given to determine an answer

Explanation:

The equation for solubility is written as

When we initially have Sr+2 ions present in then the solubility will decrease as initially present Sr+2 ,due to common ion effect, make the reaction less favourable in forward direction and hence solubility will decrease in as compared in water where no Sr+2 ions are present initially.

Therefore,

The molar solubility of will be lower in 0.10 M 0 M because of is the correct statement

The molar solubility of SrCO3 will be lower in 0.10 M 0 M Sr(NO3)2 because of Sr2+

Explanation:

The question reflects the phenomenon known in chemistry as common ion effect. Common ion effect refers to the decreased solubility of a solid in a solution that contains an ion in common with the solute.

In the case of our example here, both strontium carbonate and strontium nitrate possess the strontium II ion in common. The presence of this ion in strontium nitrate will decrease the solubility of strontium carbonate in accordance with Le Chateliers principle. Hence the answer.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
