Calculated solubility of CuO in water at T = 298.15 K and p = 101.325 kPa (initial conditions: n^o(CuO) = 1 mol, n^o (H₂O) = 1 kg (55.5084 mol), p(O₂)/p^o = 0.21).

p(CO2)/po	m(Cu)tot (mol kg−1)	pH	Im (mol kg−1)	Dominant Aqueous Cu Apecies #
4 × 10−4	7.74 × 10−6	6.41	2.29 × 10−5	Cu2+(95.8), Cu(OH)+(2.6), CuCO3 (1.0)
