Carefully remove the filter paper (it will still be very moist) and place it on a paper towel to dry overnight. A sunny window is a happy medium for wet filter paper as well. 8. Repeat the process one more time for a second trial. This time you will measure 10.0mL of 0.750M Na₂CO3 and 50.0mL of 0.250M CaCl₂ into a new plastic cup.. Don't forget your documentation!
