Question

A chemist dissolved crystals of an unknown substance into water at room temperature. He found that 33 g of the substance can be dissolved into 100 mL of water. What property of the unknown substance was the chemist most likely investigating? its solubility its rate of dissolution its chemical reaction to water its reaction to temperature changes

Answer 1

I think it is c its a chemical reaction to water

Answer 2

Answer:

He must be investigating its solubility in water.

Explanation:

Solubility is the maximum amount of a substance that can be dissolved in 100mL or 100g of water at a given temperature.

So if a chemist dissolves some amount of a crystal in 100mL then it shows that is he investigating the solubility.

The rate of dissolution will be measured only if time is also noted.

To understand the reaction one has to do some other test after reaction.

To note the temperature change the chemist must use thermometer.
