Question

Liming a lake to neutralize acid rain in it could seriously affect the availability of nutrients such as phosphate and molybdate, but not nitrate. Explain. 6. If you did not do the experiment at the beginning of this chapter, go back and try to apply the principles of this chapter to predict what would have happened at each step. Also answer the questions included. 7. Consider each of the following cations: U*; Rbt; Pbt+, and Al3+. (a) Classify the acidity of each of these cations. (b) Which of these cations give a precipitate with the CIO4 ion? (c) Which of these cations give a precipitate with the PO ion? Assume that the following elements will form oxo anions when they are in the indicated oxidation states: Te(VII); Pu(VIII); and As(III). (a) Predict the formula of the oxo anion formed by each element in that oxidation state. (b) Name each oxo anion. (c) Classify the basicity of each oxo anion. (d) Predict whether the K+ salt of each will be insoluble. (e) Predict whether the Fe3+ salt of each will be insoluble.
