Salt, sugar, and many other substances dissolve in water to form :

  1. homogenous mixture

  2. heterogenous mixture

  3. Ionic compound

  4. molecular compound


Correct Option: A
Explanation:

A mixture is a material system made up of two or more different substances which are mixed but are not combined chemically. A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties. Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures.
