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.

• increase

• decrease

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

(a)
