a) A standard ZnCl2 solution is prepared by dissolving 0.6328 g of Zn in an HCl solution and diluting to volume in a 1.00 L volumetric flask. An EDTA solution is standardized by titrating a 10.00 mL aliquot of the ZnCl2 solution, which requires 10.84 mL of EDTA solution to reach the end point. Determine the concentration of the EDTA solution. b) A 1.4927 g sample of powdered milk is dissolved and the solution titrated with the EDTA solution prepared...

PART A) A solution is prepared by mixing equal volumes of 0.17 M HCl and 0.42 M HNO3. (Assume that volumes are additive.) Express the pH to two decimal places. PART B) Using the chart Estimate [H3O+] in a 1.5 M solution of each acid. Express the molar concentrations to two significant figures separated by commas. I'm stuck on the one that says very large. For all the other ones I multiplied the Ka by the 1.5M. The answer for...
