Things which get dissolved in water are called soluble things,
e.g., salt – sugar etc. While things which are not soluble in water are called insoluble things.
For example, chalk power and sand do not get dissolved in water. These properties of objects are called solubility and insolubility respectively. Some liquids, like lemon juice is complete miscible in water while some like kerosene and mustard oil do not get completely mixed in water. Likewise, oxygen gas is partially soluble in water while few gases gets fully mixed in it.
Carbon – dioxide is completely miscible in water and hence used in soft drinks.
