Abstract

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.
