2) A professor wanted to set up a similar experiment as the one you performed in lab. He wanted to use Al(OH)3 in place of Ca(OH)2. Calculate how many mL of saturated Al(OH)3 solution it would take to titrate against 12.00 mL of 0.0542 M HCl solution. The Ksp of Al(OH)3 is 3.0x10-34. Show your work to receive credit. Finally, do you think this would be reasonable experiment for a general chemistry lab?
3) One lab section accidentally used Ba(OH)2 instead of Ca(OH)2 when they performed this experiment. The TA told them that the Ksp of Ba(OH)2 is 2.55 x 10-4. What is the molar solubility of Ba(OH)2? Show your work to receive credit.

During a lab experiment performed at STP conditions, you prepare HCl by reacting 100. ml of Cl2 gas with an excess of H2 gas. How many ml of a solution of Ba(OH)2 0.230M do you need to neutralize all the HCl produced? Please explain this in detail as I am having a hard time using STP or PV=nRT due to the lack of information provided.

1.A Chem 1211L student performed this experiment. He used 3.100 g of mixture and determined it contained 1.200 g of NH4Cl , 0.685 g of sand and 1.410 g of NaCl. What is wrong with the student’s results? What is the most likely cause of the error? 2..755 mL of a solution contains 175 mL acetone, 325 mL alcohol and the remainder is water. Calculate the % concentrations of the acetone, alcohol and water. Show all work to receive credit.
