1. CL was tasked to identify the white solid inorganic salt that Dr. Yang gave her. From her preliminary tests, the possible identities were narrowed down to the following: Zn(CN)₂ Ksp (30°C) = 7.30 x 1012 AgSCN Ksp (30°C) = 5.90 × 10 11 CL chose to investigate the solubility equilibrium of this salt and determine its identity. To a 100.0 mL distilled water at room temperature, CL added the unknown reagent until it no longer dissolves. After letting the mixture stand for 15 mins, she filtered and collected the filtrate in another beaker. From this, a 20.00 mL aliquot was drawn and was titrated with 10.20 mL of 5.00 x 10 M HCI to reach the phenolphthalein endpoint. A. Let X be the titratable species from the dissolved salt. Determine the concentration of X from the titration data. B. Based on the results of CL's experiment and the provided constants, what is the likely identity of the unknown salt? Show complete solutions to support your answer. When she submitted her report to Dr.…
