Short answer questions: 1. What is the reason why the concentration of NaCl in the ammonia brine decreases during the ammonia absorption process?
1. When two solutes that do not react chemically with each other are dissolved in the same solvent, the solubility of the two solutes is smaller than the solubility of a single solute. 2. The water vapor in the ammonia gas condenses, which reduces the concentration of sodium chloride. 3. The dissolution of ammonia water increases the volume of salt water, which relatively reduces the concentration of sodium chloride.
1. Short answer questions: 1. What is the reason why the concentration of NaCl in the ammonia brine decreases during the ammonia absorption process? Answer: ① If two solutes that do not react chemically with each other are dissolved in the same solvent, the solubility of the two solutes will be smaller than the solubility of a single solute. ②The water vapor in the ammonia gas condenses, causing the NaCl concentration to decrease. ③Ammonia gas dissolves, increasing the volume of brine and relatively reducing the concentration of NaCl.
1. If two solutes that do not react chemically with each other are dissolved in the same solvent, the solubility of the two solutes will be smaller than the solubility of a single solute.； 2. Condensation of water vapor from steamed ammonia reduces the difficulty of NaCl ； 3. Ammonia gas dissolves, increasing the volume of brine and relatively reducing the concentration of NaCl.

1. If two solutes that do not react chemically with each other are dissolved in the same solvent, the solubility of the two solutes will be smaller than the solubility of a single solute. 2. The water vapor in the ammonia vapor condenses, reducing the NaCI concentration. 3. Ammonia gas dissolves, increasing the volume of brine and relatively reducing the concentration of NaCl.

Water vapor from evaporated ammonia condenses, reducing the concentration of NaCl ； 3. The dissolution of ammonia gas increases the volume of brine and relatively reduces the NaCl concentration.
answer: First, if two solutes that do not react chemically with each other are dissolved in the same solvent, the solubility of the two solutes will be smaller than the solubility of a single solute. Second, the water vapor in the ammonia vapor condenses, reducing the concentration of sodium chloride. Third, ammonia dissolves, increasing the volume of brine and relatively reducing the concentration of sodium chloride. 1# 9067jxhuas
