Select either True/False to state whether the following definition is correct for the following term/principle (i.e. if it is correct, select "True"): Common lon Effect: The solubility of a material is unchanged when at least one of its conjugates are also present in the solution. True False Question 4 (1 Select either True/False to state whether the following definition is correct for the following term/principle (i.e. if it is correct, select "True"): Trend observed for the osmotic pressure of a solution: The osmotic pressure of a solution defined as the pressure required to encourage ion flow across a semipermeable membrane. This is known as a colligative property. True False

In order to prepare 50.0 mL of 0.200 M 3. In order to prepare 50.0 mL of 0.150 M 4. In order to prepare 50.0 mL of 0.100 M HC₂H3O2 you will add mL of 1.00 M HC₂H₂O₂ to HCl you will add H₂SO4 you will add 5. In order to prepare 40.0 mL of 0.100 M NH3 you will add 6. In order to prepare 50.0 mL of 0.100 M NaCl you will add___ grams of NaCl to mL of water. 7. In order to prepare 50.0 mL of 0.100 M C12H22O11 (sucrose) you will add grams of C12H22O11 to mL of water. NOTE: The final volume is the sum of the concentrated solution plus the volume of added water. When making solutions from solids, since the solid dissolves in the water with minimal volume change, the volume of the final solution is the amount of water you need to use. Part Two 8. Measurement of Acidity a. 0.100 M NaOH b. 0.200 M HCI c. 0.150 M…
