The sedimentation method can be used to separate sand and salt, so we pour the mixture into the water and stir it, the salt dissolves in the water and the sand settles. But it will be safer to separate river sand from the salt solution using the filter method, this can be done with a paper filter and a funnel. In this case, the salt solution passes through the paper filter, sand settles on it, sand in this case is the precipitate, and the salt solution is the filter. The salt can be separated from the filter using the evaporation method. To do this, this mixture is heated, the water evaporates, and the salt remains on the walls of the ceramic cup. Salt can also be isolated from the filter by evaporation, that is, partial evaporation of the liquid, In this case, a more concentrated solution is obtained, which upon cooling gives a precipitate in the form of a salt
