60g of sugar is added to 100 g of water. to make 160g of syrup Which of the following is correct?

• sugar is the solvent, water is the solution and syrup is the solute

• sugar is the solvent, water is the solute and syrup is the solution

• sugar is the solute, water is the solvent and syrup is the solution

• sugar is the solution, water is the solvent and syrup is the solute

A solution that contains the maximum amount of dissolved solute at a given temperature and pressure. Any additional solute added will remain undissolved, forming a precipitate.

A student dissolves 200 g of sugar in 100 g of water at 20°C. If the water is heated, will the amount of sugar that can dissolve increase or decrease?

• increase

• decrease

A solution that contains a relatively large amount of solute dissolved in a given amount of solvent.

Which is more soluble in water at 20°C, sugar or salt?

• sugar

• salt

Which syrup solution is the sweetest, meaning it has the highest concentration of sugar?

• 60 g of sugar in 100 g of water

• 40 g of sugar in 150 g of water

• 75 g of sugar in 250 g of water

• 90 g of sugar in 300 g of water

A solution that contains less solute than the maximum amount that can dissolve in a given amount of solvent at a specific temperature.

The graph displays multiple solubility curves. Which solute has the lowest solubility in water at 90°C?

• 1

• 2

• 3

• 4

A solution that contains more dissolved solute than would normally be possible at a given temperature.
