At 20°C, the solubility of salt is 36 g. At present,100 g and 200 g of saturated salt solution at 20°C are evaporated off 10 g of water at the same temperature. Algorithm Process and Text Analysis At 20°C, the solubility of salt is 36 salt is 36g. At present,100g and 200g of saturated salt solution at 20°C can evaporate 10g of water, and what are the precipitated crystals? To calculate the process and text analysis
At a temperature of 20.d egree. C., the solubility of salt is 36 g, i.e. a maximum of 36 g of salt is dissolved in 100 g of water
At present,100 g and 200 g of saturated salt solution at 20.d egree. C. were evaporated off 10 g of water each at a constant temperature, and the precipitated crystals were 3.6 g and 3.6 g, respectively
Since the same solution is saturated,3.6 g of salt crystals are dissolved in every 10 g of water, so 3.6 g are eluted
At a temperature of 20°C, the solubility of salt is 36 g, i.e. a maximum of 36 g of salt is dissolved in 100 g of water
At present,100 g and 200 g of saturated salt solution at 20.d egree. C. were evaporated off 10 g of water each at a constant temperature, and the precipitated crystals were 3.6 g and 3.6 g, respectively
Since the same solution was saturated,3.6 g of salt crystals were dissolved per 10 g of water, so 3.6 g were eluted
At a fixed temperature, there is 100 grams of saturated solution and the solubility of salt is 36 grams. Since it is 100 g of saturated solution, that is to say the mass of solute + the mass of solvent =100 g The amount of salt that can be dissolved in 100 grams of solvent is 36 grams, that is to say, in saturated salt solution, the mass of solution is equal to 136 grams, that not contradictory?

It can be calculated according to 36:100.100 is equal to solvent and solute. That's right, but this is not hard to cover according to solubility. Solubility is only a concept and a proportion!
Solubility is really defined as 36:100 equal to sodium chloride: water, at this ratio can be calculated in this condition any mass of saturated salt solution solute and solvent!
Calculate according to 36:100,100 is equal to the solvent plus solute, yes, but this can not be hard according to solubility, solubility is only a concept a proportion!
