Correct! This is a soluble ionic compound that dissociates into ions (charged particles).
Incorrect. This is a soluble ionic compound that dissociates into ions (charged particles).
PbI2 in H2O
Correct! This is an ionic compound, but it is insoluble and does not dissociate in water to form ions (refer to your STAAR chart for solubility rules).
Incorrect. This is an ionic compound, but it is insoluble and does not dissociate in water to form ions (refer to your STAAR chart for solubility rules).
Distilled H2O
Correct! Water is a covalent compound and does not contain ions.
Incorrect. Water is a covalent compound and does not contain ions.
Insoluble compounds in water
Correct! Insoluble compounds do not dissolve or dissociate in water; therefore, they do not produce free-floating ions.
Incorrect. Insoluble compounds do not dissolve or dissociate in water; therefore, they do not produce free-floating ions.
