- In a 50 mL Erlenmeyer flask were combined at 25 ◦C 10 mL of water, 1.482 g of chromium (III) chloride hexahydrate, 1.75 mL of 2,4-pentanedione (C5H8O2), and 1.214 g of sodium acetate. After stirring for 30 minutes, 1.204 g of solid tris(2,4-pentanedionato)chromium (III) (Cr(C5H7O2)3) was isolated. The density of 2,4-pentanedione at 25 ◦C is 0.975 g/mL. The equation for the reaction is shown below.
Cr3+(aq) + C5H8O2 (aq) + C2H3O2−(aq) → Cr(C5H7O2)3(s) + HC2H3O2(aq)
- How much of each product can theoretically be produced?
- What was the percent yield of the product?
- How much of the non-limiting reactants are left after the reaction?
