mixtures can sometimes be difficult to separate and various chemistry techniques have been developed to achieve separation. examine the filtration technique in the diagram. what is the underlying basis for why this technique works to separate the different substances in a mixture? gravity pulls on one of the substances more than the other. the substances have different chemical reactions with the filter paper. the size of one substance can fit through the filter and the other substance cannot. the particles have different weights and the heavier one will stay on top of the filter while the lighter one sinks into the filter.

Answer

Explanation:

Step1: Understand filtration principle

Filtration separates substances based on particle size.

Step2: Analyze water - sand mixture

In a water - sand mixture, water particles are small enough to pass through the pores of the filter paper, while sand particles are too large.

Step3: Determine separation basis

The basis for separating the substances in the mixture is the difference in particle size.

Answer:

The underlying basis for separating the different substances in the mixture is the difference in particle size, where smaller particles (water) can pass through the filter paper and larger particles (sand) are retained.
