1. It will dissolve in hot tea because the temperature can dissolve more of the solute the higher it is. The higher temperature causes an unsaturated solution.
2. 45 g.
3. (a). 200
(b). 710
(c). 1892
4. (a). 37, 31, 32
(b). 170, 50, 39
5. A saturated solution is a solution in which the solvent has dissolved as much solute as it can retain stably at a specified temperature. An unsaturated solution is a solution containing a lower concentration of solute than a saturated solution contains at a specific temperature.
6. (a). 30 g
(b). Unsaturated
(c). 35 g
7. (a). The crystal will dissolve into the solution.
(b). The crystals will remain undissolved at the bottom of the solution.
(c). Solid crystals will form and settle to the bottom of the solution.
8. 1.5 multiplied by 35 g= 52.5%
