Describe a procedure for making 100 mL of a 0.10 M solution of barium nitrate, Ba(NO3)2. Make sure to include all equipment and amounts of materials you will need.
The sample is diluted with 72.178 g of water. A 14.024 g aliquot of this solution is then titrated with 0.1097 M HCl. It required 29.55 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
Calculate the pH of a buffer formed by mixing 85 ml of 0.12 M lactic acid with 95 ml of 0.15 M sodium lactate.
