A student used H₂SO4 to find concentration of Sr²+ in a solution A via precipitation method. For 100 ml of solution A, the student added 20 ml of 1M H₂SO4, marked as solution B, waited for precipitation, decanted the liquid, and finally got 1.03 g of dried SrSO4. The student also collected the decanted liquid and labeled as solution C. Hint: Ksp of SrSO4 = 3.44 x 10-7 1. Find concentration of Sr²* in solution A. 2. Find concentration of Sr²+ in the decanted solution C after precipitation and decanting solution B. 3. Compare [Sr²+] in solution A and decanted solution C. Does your result make sense?
