Abstract: | Measurement of solubility as a function of pressure allows calculation of . Using this experimental approach, the best estimate of for the dissolution of aged amorphous silica in salt water or seawater at 0–2°C is ?9.9 cm3 mol?1 (standard error = 0.4 cm3 mol?1). This gives , which compares well with other published values of . |
