What Is The Solubility Of Sodium Hydrosulfite In Water At Different Temperatures?

The solubility of sodium hydrosulfite in water varies with temperature. At 0°C, the solubility is approximately 42 g/100 mL of water. As the temperature increases, the solubility also increases. At 20°C, the solubility is approximately 70 g/100 mL of water, and at 100°C, it is approximately 185 g/100 mL of water. It is important to note that the solubility of sodium hydrosulfite can also be affected by factors such as pH and the presence of other substances in the solution.
