Salt dissolved in water is a solution, therefore _____.
saveliy_v [14]

Answer: Correct options are as follows.

  • salt is not chemically bonded to water.
  • salt and water retain their own chemical properties.

Explanation:

When salt is dissolved in water then it means that it is a physical change as salt has completely dissociated into ions but they are not chemically combined to the water molecules.

As a result, both salt and water will retain their chemical properties.

For example, NaCl when dissolved in water will dissociate as follows.

           NaCl \rightarrow Na^{+} + Cl^{-}

Only the particles of salt have evenly distributed in water.

And, when a components of a salt chemically combine with another substance then it will form a new compound.

Therefore, we can conclude that salt dissolved in water is a solution, therefore:

  • salt is not chemically bonded to water.
  • salt and water retain their own chemical properties.

When does a phyisical change occur?
ioda
Physical changes occur when objects or substances undergo a change that does not change their chemical composition. This contrasts with the concept of chemical change in which the composition of a substance changes or one or more substances combine or break up to form new substances.
