2) We went over lab quiz we took on friday
- Molarity= unit of concentration
- Use formula to determine how many mols of solute needed to make 0.15 M of solution
- If you need help with the formula use this video as a reference: http://www.youtube.com/watch?v=8oTqwBAvbnY&feature=fvwrel
.015 mol NaCl
58.44g NaCl
1 mol NaCl
- Fill beaker with 50 mL of water
- Then mix in .88g of Solute (NaCl)
- Then fill rest of the beaker to 100 mL
3) Went through IV. Solubility Notes
-
- Soluble in water= dissolves in water (aqueous)
- In soluble= does not dissolve in water (solid)
- There are some exceptions though, mentioned on the sheet
4) Went through V. Solubility Practice #1-3:
-
- If the balanced equation has aqueous on both sides, then no reaction has taken place
5) Homework are questions #1 and #2 on the ChemThink precipitate lab sheet we picked up in
class. Use www.chemthink.com to answer the questions under Solubility
