- What is the difference between a colloid, and a solution?
- What mass of sodium dichromate is required to prepare a #250*mL# volume of #0.050*mol*L^-1# concentration with respect to dichromate?
- If a crystal added to an aqueous solution causes many particles to come out of solution, what can be said about the original solution?
- A solution is prepared to be 0.1475 M in Sr(OH)2. How do you find the [H3O+], [OH‐], pH, and pOH?
- When sugar is added to water, the sugar dissolves and the resulting liquid is clear. Do the sugar and water form a pure substance, or do they form a mixture?
- What effect does a solute have on the freezing and boiling points of the solution?
