Question

Which is something that a PURE SUBSTANCE and a SOLUTION have in common?

A) They both are made of one kind of particle.
B) They both are made of different kinds of particles.
C) They both look speckled or chunky.
D) They both look uniform (the same) throughout.

Answer 1

D) They both look uniform (the same) throughout.

Further explanation

Pure substance can be any element or compound and is formed from one type of atom/molecule only

Meanwhile, the solution is included in a mixture consisting of 2 or more pure substance

Pure substance can be formed through a chemical process while the mixture is through a physical process

Mixture can be separated by physical processes into components of pure substance while pure substance cannot

The mixture itself consists of a homogeneous and heterogeneous solution

The mixture can be divided into a homogeneous mixture if the composition/ratio of each substance in the mixture is the same and a heterogeneous mixture if the ratio of the composition of the substances is not the same (can be varied) in each place.

Mixtures can also be divided into solutions, suspensions, and colloids based mainly on the size of the particles

Homogeneous mixture = Solution

Heterogeneous mixture = suspension, and

The mixture is located between suspension and solution = Colloid
