Unit 10 Water and Solutions

You will need a calculator, solubility rules chart and solubility curves graph.

Describe the unique role of water in solutions in terms of polarity.

Water is polar (positive hydrogen atoms, negative oxygen atom).
water is the universal solvent and dissolves other polar molecules.

Multiple Choice

Which of these molecules represents water with the correct charges?

Multiple Choice

Water is polar and considered a universal solvent, oil does not dissolve in water so it must be..

polar

non-polar

universal solvent

no idea

Multiple Choice

Water is polar and considered a universal solvent, which of these is NOT soluble in water?

Sugar

Salt

Bacon Grease

Lemon Juice

Solubility Rules

You should be able to determine if a substance is soluble or insoluble in water.

You should also be able to identify a precipitation reaction.

Multiple Choice

Is CaBr₂soluble or insoluble?

Soluble

Insoluble

Multiple Choice

Is HgI₂ soluble or insoluble?

Soluble

Insoluble

Multiple Choice

Is Ca(OH)₂ soluble or insoluble?

Soluble

Insoluble

A precipitation reaction happens when two dissolved substances in water mix together and form an insoluble solid that sinks to the bottom. That solid is called a precipitate.

Multiple Choice

Does this reaction form a precipitate?

Yes, because of BaSO4

Yes, because of NaCl

Yes, because of BaCl2
