Cualidad de una sustancia que es percibida por el sentido del gusto. es un pesticida que no altera el olor ni el sabor de los frutos tratados
Sea, tap, river, surface and lake water all contain some dissolved solids and are therefore weak solutions. Pure, distilled and de-ionised water is a pure substance and is often used as a Solvent.
Salt (or other solutes, like sugar) can easily dissolve in liquid water. However, taking the solute out of the water and putting it in the gas phase (air) requires a lot of energy. At temperatures around the water boiling point, these solutes stay in the liquid. Now the total pressure in the liquid and the air at the boundary are the same- otherwise one would push the other into a smaller space. Part of the pressure in the liquid comes from the solutes, not the water. So the pressure due to the water alone is reduced compared to that of pure water at the same temperature.
