How do solutions differ from other mixtures?

a.
solutions are heterogeneous mixtures.

b.
solutions do not contain more than one element.

c.
each component of a solution can be seen clearly.

d.
one component of a solution dissolves in another.

The correct answer is D. One component of a solution dissolves in another.

Explanation:

In chemistry, a solution is generally a homogeneous mixture which means it integrates to or more substances and the result is uniform. This type of mixture is formed as one substance (solute) is dissolved into another (solvent). For example, as you dissolve sugar in water the water acts as a solvent while the sugar acts as a solute. Besides this, elements in a solution cannot be easily separated, neither the components can be seen and the solution is stable. According to this, solutions are different from other mixtures because "One component of a solution dissolves in another" because only in solution there is a solute and a solvent.

b is the correct

a is the correct answer
