solubility and net ionic equations

An aqueous solution is:

• any liquid with another compound dissolved in it.

• an ionic compound with water dissolved in it.

• water with another compound dissolved in it.

• none of the above

Which of the following compounds is SOLUBLE?

• copper carbonate

• calcium carbonate

• potassium carbonate

• strontium carbonate

Which of the following compounds is INSOLUBLE?

• magnesium phosphate

• magnesium sulfate

• magnesium iodide

• magnesium nitrate

• none of the above

Explain the solubility of ionic compounds.

• Ionic compounds are soluble in water due to the attraction between the ions and water molecules.

• Ionic compounds are soluble in air due to the attraction between the ions and air molecules.

• Ionic compounds are insoluble in water due to the repulsion between the ions and water molecules.

• Ionic compounds are soluble in oil due to the attraction between the ions and oil molecules.
