an aqueous solution of Ca(OH)2 with a concentration Ca(OH)2(ag)+2HC1 (aq)CaCl, (ag)+H,O() An aqueous solution of Ca(OH)2with a concentration of 0.164 M was used to titrate 25.00 mL of aqueous HCI. 16.53 mL of the Ca(OH)2was required to reach the endpoint of the titration. ACID-BASE TITRATIONS Introduction Pt A titration is the sequential addition of reactant to a solution containina other Part 1 (1 point) How many moles of base were required to react completely with the acid in this reaction?...
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?
