Answer: Water
Explanation:
Chemically speaking, a solution has two components: solute and solvent.
The <u>solute</u> is that substance (usually solid, but it can also be liquid or gas) that dissolves in a liquid substance and <u>its proportion in the resulting solution is usually less than the solvent.
</u>
The <u>solvent</u> is the substance used to <u>dissolve the solute, and generally its proportion in the resulting solution is greater.</u> Being the most common used solvent water.
This means that in a solution there is usually more solvent than solute.
So, in the case of the hydrogen peroxide solution, since the proportion is
to
, the hydrogen peroxide is the solute and water is the solvent.
