4. (10 pts) You want to supply a soil with copper at a rate of 3 lb ac-1, using copper sulfate (CuSO4 . 5 H2O; 25% Cu, 13% S) a. (4 pts) Compute how many kg fertilizer ha-1 you would need to meet that target. b. (4 pts) If you want to meet a S requirement of 50 kg ha-1 instead, compute how much copper sulfate you would need, and how much copper you would add (all in kg ha-1). c. (2 pts) In 50 words or less, explain why meeting a S requirement with copper sulfate is a not a great idea

1. Your group will need approximately 6 g of the copper ammine complex to perform the analyses. The general formula for the copper ammine complex is [Cu(NH3)x]SO4•H2O Calculate the formula weight for several values of x, x=2 through x=6. 2. You will need to prepare about 6 g of the copper ammine product. Estimate how much CuSO4•5H2O you should start with to prepare approximately 6 g of the copper ammine complex. 3. Calculate how many grams of copper sulfate pentahydrate...
