Yes, the sample will still be a heterogeneous mixture.
A mixture contains two or more substances in any proportion.
Mixtures are divided into two main groups:
This shows that a homogeneous mixture has only one single phase.
It is either in a solid or liquid or gaseous phase.
A typical example is air which contains a mixture of gases of the same phase.
This means that a heterogeneous mixture can contain constituents of different or the same phase but in different quantity.
A typical example is a mixture of sand and grains. Both are of a solid phase but are combined together in different quantity even when the size of the grain is the same with the sand.
Therefore, the sample will still be a heterogeneous mixture.
