Question
Indicate which is the solvent and which is the solute in the following: Solvent Solute a. 50 mL H_2O and 10 g sugar b. 150 mL H_2O and 50 mL isopropyl alcohol c. 150 mL H_2O and 250 mL isopropyl alcohol Explain how stirring a solution would effect the rate of dissolving. Explain how heating a solution would effect the rate of dissolving in terms of what happens to the molecules. Reagents, A, B, and C, where tested with each other to determine their relative density using the procedure from Part 3. The following observations were made. Using the results, list the 3 reagents in order of increasing density.Explanation / Answer
1)
A solvent is a liquid that dissolves a solid, liquid or gaseous solute. A solute is a substance dissolved in solvent. A solute and a solvent make up a solution. The solute is usually present in a smaller amount than the solvent.
a) H2O is solvent sugar is solute
When dealing with liquid-liquid solutions, the liquid ingredient in greatest concentration is the solvent and the liquid ingredient is lesser concentration is the solute
b) H2O is solvent isopropyl alcohol is solute
c) isopropyl alcohol is solvent H2O is solute
2) stirring increases the rate of dissolving, when we stir, more area of solute is exposed to the solvent more surface area means more solubility. hence there is increase in rate of dissolving.
