1) A portion of 50.00 ml HCL solution requires 29.71 ml of 0.01963 M Ba(OH)2 to reach the end point. Determine the molarity for HCL.
2) Calculate the molar solubility of Ba(IO3)2 in a solution that us 0.02 M in Ba(NO3)2
3) determine the grams of Ba(IO3)2 that can be dissolved in 500 ml of H2O at 25oC. Ksp= 1.57x10^-9
