Phenolphthalein turns pink in solutions that are roughly 1.0x10-5 M in hydroxide ions. The only source of hydroxide ions is your Ca(OH)2. Let's assume that the amount of water left behind in the beaker to test for complete transfer is about three drops or 0.15 mL. How many moles of Ca(OH)2 would be present in those three drops if the solution barely turned pink? How many grams of Ca(OH)2?
How many moles of Ca(OH)2 are present in 849 mL of 1.26 M Ca(OH)2?
