Temperature Dependence of Cu(II) Carbonate Complexation in Natural Seawater
Digital Object Identifier (DOI)
Cu(II) carbonate complexation was examined in natural seawater between 5° and 35°C. The reaction enthalpy for the equilibrium Cu2 + CO32− ⇌ CuCO30, expressed in terms of total carbonate ion concentration, is ∼2.5 kcal mol−1. The formation constant swβ1 = [CuCO30] [Cu2+]−1CO32−]T−1, expressed in terms of total carbonate ion concentration in seawater, thus decreases by about 25% between 25° and 5°C.
