What increases the rate of dissolving a solid and factors that affect the rate of solubility of a solid into a liquid agitation temperature and surface area?
Dissolution depends on the Surface exposition tô The solvente and solvent renewal on the surface. Stirring improves the liquid renewal on The solid surface.also, grinding a solid improves the specific Surface área of The sólidos. Só you can dissolve faster small solid partições under agitation. But remember that maximum solubility at a certain temperature depends of the Nature of the solid and the solvent and obey thermodynamical laws
Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases. Surface area does not affect how much of a solute will be dissolved, but it is a factor in how quickly or slowly the substance will dissolve. Apart from the nature of solute and solvent, temperature also affects solid solubility considerably. If the dissolution process is endothermic then the solubility should increase with an increase in temperature. Solubility is affected by 4 factors – temperature, pressure, polarity, and molecular size. Solubility increases with temperature for most solids dissolved in liquid water. This is because higher temperatures increase the vibration or kinetic energy of the solute molecules. The stirring allows fresh solvent molecules to continually be in contact with the solute. If it is not stirred, then the water right at the surface of the solute becomes saturated with dissolved sugar molecules, meaning that it is more difficult for additional solute to dissolve. The solubility of a solid in a liquid is significantly affected by temperature change. For most of the solids, solubility in water increases with rising temperature. As the temperature increases, the average kinetic energy of the solute molecules in the solution also increases. When it comes to solid solutes, increasing the temperature will increase the rate of dissolving. As heat is added, the solute particles move around more, getting closer to the solvent molecules. This makes helps the solid dissolve faster in a liquid. The addition of more heat facilitates the dissolving reaction by providing energy to break bonds in the solid. This is the most common situation where an increase in temperature produces an increase in solubility for solids.
