Answer:
Explanation:
This experiment demonstrate that a plant don't need only water to grow and increase its mass.
A plant will also need nutrients located in the soil that will help it grow and increase its mass.
The students can determine which of the solutions contains salt through the conductive tester.
<h3 /><h3>What is an ionic solution?</h3>
It is a solution containing ions are atoms that have gained or lost electrons to acquire a positive (lost electron) or negative (gained electron) charge.
An ionic solution would be able to conduct electricity whereas the covalent would not so if you have a conductivity tester which is available in most labs.
The students can distinguish between the 2 solutions through the conductive tester.
