Mixture in water. Beaker on the left contains water. Weighing boat in the centre has a mixture of two solids, salt (sodium chloride, NaCl) and sand (mostly silica, SiO2). When the mixture is added to water in the right beaker and stirred, salt dissolves and forms a clear solution, while sand does not dissolve and settles at the bottom. | |
