Answer:
You should not use an open flame to heat the solvent and the solvent should be heat in a stoppered flask to vapour away from the open flame
Explanation:
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.
The exercise increases the rate at which the solution change to color yellow.
BTB [ Bromothymol blue] is an acid indicator that is used to measure the quantity of carbon dioxide that is produced after exercising for a specified period of time. The presence of carbon dioxide turns the blue solution to yellow. The higher the quantity of carbon dioxide present, the higher the rate at which the solution turns to yellow.
