Problem 18.112

When 25.0 mL of a solution containing both Fe21 and Fe31 ions is titrated with 23.0 mL of 0.0200 M KMnO4 (in dilute sulfuric acid), all of the Fe21 ions are oxidized to Fe31 ions. Next, the solution is treated with Zn metal to convert all of the Fe31 ions to Fe21 ions. Finally, 40.0 mL of the same KMnO4 solution are added to the solution in order to oxidize the Fe21 ions to Fe31. Calculate the molar concentrations of Fe21 and Fe31 in the original solution.

Step 1 of 3

EXTERNALITIES & PROPERTY RIGHTS ● negative externality = when part of the cost of an activity falls on people not pursuing the activity ● positive externality = when some fraction of the benefit of an activity is received by people not participating in the activity ● if the market equilibrium quantity is greater than the socially optimal quantity, one can infer that… there is a negative externality associated with this good ● if the external benefit of an activity is added to the private benefits, then the demand curve shifts right ● an external benefit implies that private markets will provide too little of the good (relative to the social optimum) and an external cost implies that private markets will provide too much of the good ● the major implication of the coase theorem if that individuals can solve many externalities if they can buy and sell the right to generate the externality ● the optimal quantity of a negative externality is zero if the marginal cost of reducing it is zero ● tragedy of the commons = overuse of resources that have no price ● examples of positional arms control agreements: ○ campaign spending limits ○ binding arbitration agreements ○ social norms against vanity ● people who engage in activities that generate positive externalities will tend to engage in those activities less than socially optimal ● the market equilibrium level of output occurs where private demand intersects MC ● for nega
