In a cup of sweet tea, which part is the solvent? What is a saturated solution? What happens to the solubility of most solids when the water gets hotter? A solution has 12 g of solute in 0.40 L. What is its concentration? 250 mL expressed in litres is Which change does not increase the maximum mass that can dissolve? Why does a warm fizzy drink go flat faster than a cold one? A hot saturated solution cools and crystals appear. Why? Which statement about dissolved sugar is correct? Why does a sugar lump dissolve slower than the same mass of granulated sugar? Define solute. — The substance that dissolves. Define solvent. — The liquid that does the dissolving. Define a saturated solution. — Holds the most solute that can dissolve at that temperature. Define solubility. — Maximum mass dissolving in 100 g of water at a stated temperature. Concentration formula in g/L? — Mass of solute (g) divided by volume of solution (L). How do you convert mL to L? — Divide by 1000. Effect of heating on most solids' solubility? — It increases. Effect of heating on gas solubility? — It decreases. Three ways to dissolve faster? — Stir, heat, crush the solid. Why do crystals form on cooling? — Cooler water holds less solute. Keep going with Lina
