An unknown sample was tested for its anion and cation components. For the cation test, it gave a blue solution upon the addition of excess NH3. For its anion test, it formed a precipitate upon the addition of Ba(NO3)2, and CH3COOH was added to its precipitate which resulted in no reaction. What is the identity of the salt in the solution? O a. Fe₂(SO4)3 O b. CuSO4 O C. FePO4 O d. CU3(PO4)2 An unknown solution formed a white precipitate upon the addition of 1.0M NaOH, but no precipitate was formed when NH³ was added. What could be the ion present in the solution? O a. Ca²+ O b. Fe³+ O C. Zn²+ O d. Cu²+

You are preparing standard acid and base solutions for the laboratory, using potassium hydrogen phthalate (KHC₈H₄O₄, abbreviated KHP) as the primary standard. KHP (molar mass = 204.22 g/mol) has one acidic hydrogen. You prepared solutions of both NaOH and HCl. It took 22.65 mL of the NaOH solution to titrate (react exactly with) 1.55 g KHP. It then took 32.35 mL of HCl solution to titrate 25.00 mL of the NaOH solution. What is the molarity of the HCl solution?
