Question

can yall help me with all four questions please?

Consider these compounds A. MgCO3 B. AgzCO3 C. MnS D. MgF2 Complete the following statements by entering the letter(s) corresponding to the correct compound(s). (If more than one compound fits the description, include all the relevant compounds by writing your answer as a string of characters without punctuation, e.g, ABC.) Without doing any calculations it is possible to determine that manganese(Il) carbonate is more soluble than , and manganese(I) carbonate is less soluble than It is not possible to determine whether manganese(I) carbonate is more or less soluble than simply comparing Ksp values. by

Answer 1

Solubility product is the product of concentrations ions present in a saturated solution. If Solublity of a substance​ is more, higher will be it's solubility product. It is possible to comparing the solublities of two substances by comparing their Solublity products.

Solublity products of given substances are in the following order. MgCO3> MgF2 >Ag2CO3>MnS.

Hence magnesium carbonate is more soluble than magnesium fluoride, silver carbonate and Manganese sulphide.

2) Solublity products of given substances are in the following order.

ZnCO3> BaCrO4>PbCO3>Fe2S3>Ca3(PO4)2.

Hence zinc carbonate is more soluble than barium chromate, lead carbonate, ferriF sulphide and calcium phosphate.
