Document Summary
Page 2 of 9 (you can use it for scratch paper, long responses, etc) Multiple choice questions (10 points each, 40 total: in an open container on the earth"s surface a professor weighs 2. 373(5) g of caco3 and adds it to 1. 0000(7) Which of the following errors in a calculation of the final molarity co3 all correct answers. Circle: the professor weighs the caco3 properly but forgets to treat the acid-base properties of co3. Express the ph of the resulting solution in terms of the pka for. Ha. (b) take the solution (0. 5l) and add enough of a 1m strong acid solution to the mixture to set the ph equal to the pka. What is the volume of the final solution? (c) repeat step b, adding the acid solution in 4 equal increments. Sketch below the resulting titration curve of ph versus of strong acid added, labeling the axes and unique points along the way as titrant solution is added.
