What is the calculation of the concentration of the solution?
Solution mass = reactant mass total - the quality of the generated gas - the quality of generating precipitation or the solute mass / solute mass fraction; preparation of the general preparation steps of the solution in the laboratory:1. according to the solute mass fraction: calculation, weighing, taking, dissolving and bottling labels2. according to the amount of substance concentration: calculation, weighing, dissolving, cooling, moving, washing, fixing and shaking
Gas solubility is the volume of a gas dissolved in 1 volume water when it reaches a saturation state at a pressure of 101kPa and a certain temperatureCalculate solution mass = solute mass + solvent massBut the solution volume < solute volume + solvent volumeMass fraction of solute = solute mass / solution mass * 100%Solute mass = solution mass = mass fraction of solute
Solubility: the solubility of a solid substance at a certain temperature when it reaches a saturation state in a 100g solvent. If the solvent is not specified, the solubility in general is defined as the solubility of the substance in water
