how would the following errors affect the mass of calcium phosphate precipitate recovered in this experiment? Would they increase it, decrease it or would it remain the same? Explain? (a) The buret was not rinsed with CaCl2 solution after cleaning at the start of the experiment. (b) The filter paper was still wet when you weighed the final product on filter paper. (c) You mixed up the initial volumes of the two solutions and used 30. 0 mL of the unknown CaCl2 solution and only 20. 0 mL of the 0. 100 M Na3PO4 solution.
