Ca3(PO4)2- Increase in solubility

Barium hydroxide- increase in solubility

Magnesium carbonate- increase in solubility

Copper II sulphide- increase solubility

Lead II bromide- increase solubility

CuI - increase solubility

Explanation:

Calcium phosphate solubility is pH dependent. At lower pH, calcium phosphate is more soluble in water while at pH above 8.5, the solubility of calcium phosphate decreases markedly.

For Barium hydroxide and magnesium carbonate,decreasing the pH will increase the solubility of the compound.

For copper II sulphide,decreasing the pH will lead to a greater solubility. Also, lead II bromide is ordinarily insoluble in water but it's solubility increases with decreasing pH.

CuI is insoluble in water but soluble in dilute hydrochloric acid.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
