Does calcium sulfate dissolve in water
Web1 day ago · The acidification of seawater dissolved the generated calcium carbonate and increased the concentration of calcium ions in seawater. Among them, the pH of soybean urease after solidification is lower than that of the other two enzyme sources, resulting in a higher dissolution of calcium carbonate. WebThe solubility product of calcium sulfite was first determined by Marusawa (13,21) to be 4.4 x 10-7 mo1 2 dm-6 (molarity scale) at 291.2 K, on the assumption of incomplete dissociation of the dissolved calcium sulfite. From Debye-Huckel theory, a value of 3.66(2) x 10-7 mo1 2 dm-6 can be obtained from the original data given by Narusawa (13).
