heterogeneous because of the dust particles it contains Other salts like bromides and gypsum are more soluble than carbonates but still not as soluble as sodium chloride or potassium and magnesium-based salts. Sodium chloride is a chemical compound, not a mixture; NaCl is homogeneous. We cannot separate the atoms of a constituent particle by any physical methods. Any given spoonful of soup will contain varying amounts of the different vegetables and other components of the soup. Most of substances in the world are mixtures. Even if the particles are not too big, it is possible that the quantity is too much, resulting in insufficient dissolution. Already a member? These can be separated by distillation in a laboratory using a burner placed under a beaker containing the salt water. Element: a substance that is made up of only one type of atom. You can use a mechanical method to separate components of a heterogeneous mixture (e.g., sorting candies in a bowl or filtering rocks to separate them from sand).

It cannot be physically separated into its components, #"Na"^(+)# and #"Cl"^(-)#. Mix them together and you will find that the salt and water become completely inseparable. Sodium is a chemical element, so it is a pure substance. Even if the salt is difficult to dissolve, increasing the temperature can increase the solubility. In other cases, you need to look more closely to recognize this mixture. Sodium chloride is a pure substance; it cannot be separated into its chemical constituents sodium and chlorine by a physical process. A large part of which kind of mixture saltwater is can depend on the kind of saltwater that you want to use, such as a homemade salt solution or seawater. Pure substances in which constituent particles are composed of the one type of atoms are called elements. Similarly, the constituent particles of pure water are its molecules (H2O).
