How do you dissolve the solute quicker, also if there's powder in the bottom, is it saturated or what? (below)

Question

Laura observes her friend Ingrid preparing to make a glass of lemon iced tea from a drink mix. Ingrid first fills a tall glass with ice cubes. She then adds a spoonful of drink mix and 2 sugar cubes to the glass before adding cold tap water. A considerable amount of undissolved solid remains at the bottom of the glass.

(a) Describe four suggestions that Laura could make to reduce the amount of undissolved solid.

(b) Is Ingrid's FIRST drink saturated, unsaturated, or supersaturated? Explain.

(c) If Laura's suggestions are taken and there is no evidence of undissolved solid in the glass, how would you now describe the drink?

Thanks a lot!!! :)

Answer 1

(a) - stir it

      -add the ice cubes last

      -add the solid more slowly

      -use more water/less ice

(b) -unsaturated, because if she stirred it the solid might all

       desolve

(c) -unsaturated because all the solid was desolved in water

I am no good at chem. and these are just guesses.  But it's what I'd think.

Answer 2

sugar needs heat to dissolve in water...

to determine saturation you need to know the chemical composition of the substances involved.... but both should be unsaturated. for the second to be saturated you'd have to add the 'magic' amount.
