It will be saturated salt solution with salt crystals at the bottom of the container.
dilute salt in water to form a solution, then evaporate the water and you are left with salt crystals - gamemaster12321
Examples of concentrated solutions include concentrated hydrochloric acid, concentrated sodium hydroxide solution, and concentrated sulfuric acid. These solutions have a high solute concentration relative to the solvent.
Yes, the concentration of salt in a solution can affect the size of salt crystals that form when the solution is left to evaporate. Higher salt concentrations typically lead to larger salt crystals as there is more salt available to form crystals as the water evaporates. Additionally, temperature, agitation, and impurities can also influence crystal size.
If a salt precipitates upon heating a concentrated solution, the heat of solution for this salt would be endothermic. This is because the process of dissolving the salt is absorbing heat from the surroundings, leading to a decrease in temperature and the precipitation of the salt.
