Start date Oct 16, 2008

In summary, the solubility of Na2CO3 in water is approximately 22 g/100 mL at room temperature. Ag2CO3 is not soluble in water, with a very low solubility of 0.000016 g/100 mL at room temperature. The solubility of K2SO4 in water increases with increasing temperature, with a solubility of 7.1 g/100 mL at 0°C and 110 g/100 mL at 100°C. The solubility of Mg(OH)2 decreases as the pH of the solution increases, with a solubility of 0.0009 g/100 mL at pH 7 and 0.00000001 g
