The solubility of 10°C sodium gluconate is 45. According to the query of relevant public information, the solubility of sodium gluconate increases as the temperature rises. There is a linear formula where the solubility is equal to 34 plus temperature times a constant parameter one point one, that is, 34 plus 10 times 1.1 equals 45, 10 degrees glucose Sodium acid solubility is 45. Sodium gluconate, also known as sodium pentaglycolate, is a white or light yellow crystalline powder that is easily soluble in water.
