A typical hydrogen peroxide solution from a drug store is labeled as 3.0% hydrogen peroxide. What is the other 97% of this compo
GarryVolchara [31]

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 3\% to 97\%, the hydrogen peroxide is the solute and water is the solvent.

If you accidentally lost some sand when you decanted tyhe NaCl, how would the % salt calculation be affected?
skad [1K]

Answer:

Unchanged.

Explanation:

Hello,

In this case, for the experiment you performed, as you previously removed the sodium chloride, its % salt calculation will not be affected by the lost of the sand. It is important to remember that such experiments must be performed carefully as the committed error is a high-impact factor regarding to the experiment's performance. It is important for you to remember that to separate the sodium chloride, it earlier dissolution in water allowed to be dissolved leveraging the insolubility of sand in water, thus, it was decanted easily.

Best regards.
