1. Check all the equipment that apply in preparing serial and molar dilutions only - test tubes
- mohr pipette
- graduate cylinder
- stirring rod
- stock solutions in volumetric flask
- beaker
- scoopula
- balance
- volumetric pipette

2. What is the order of making a stock solution as you did making 0.1 M of NaCl (Part A) in the lab?
1. Measure grams of NaCl needed to make the 0.1 M solution at a certain volume. Place it in the 100 mL volumetric flask, using a wash bottle to clean remaining solid.
2. Cap and Invert the flask and add water up to the mark on the 100 mL volumetric flask
3. Add water about 1/2 full and swirl to dissolve solid as well as add the food coloring.
4. Transfer solution to a plastic bottle to save solution. Cap the bottle to prevent contamination.
