Halite dissolves congruently according to:  Given the equilibrium constant at 25°C, K_eq = 10^1.58, what is the solubility of halite in water at 25°C? (Hint: you will need to figure out the concentration of Na⁺ and Cl^- in equilibrium with halite separately, and sum the result to get the total solubility).

Given a global mean average runoff of 0.3 m yr^-1, and assuming this runoff is saturated with respect to halite, what is the average denudation rate of halite? How does this compare with a global average total denudation rate of 0.13 kg m^-2 yr^-1? Under what conditions would you expect to see halite outcrops on the surface?
