Answer 1

Define solute: the minor component (smaller amount) in a solution, dissolved in the solvent.

Question 2

Define solubility

Answer 2

Referring to the ability for a given substance, the solute, to dissolve in a solvent

Question 3

Name 3 things that can increase the rate of solubility

Answer 3

. Increase temperature
. Smaller particles (crushed tablet compared to whole tablet)
. Stirring the solution

Question 4

If you have 80 milliliters of vinegar and you add 20 milliliters of water. In this solution, the water is identified as what part of the solution?

Answer 4

The water would be the solute because it is the smaller amount

Question 5

Is the process of dissolving a solute in a solvent a chemical reaction or a physical reaction? Explain why.

Answer 5

Physical change because the parts never chemical combine

Question 6

Why is water described as the universal solvent?

Answer 6

The unequal sharing of electrons between oxygen and hydrogen

Question 7

Explain what happens to solubility when you increase the temperature.

Answer 7

As you increase temperature the solubility increases

Why is water described as a polar substance?

Answer 8

. A positive end and a negative end

. Positive charge

Question 9

What most impacts whether a substance will dissolve will dissolve in water?

Answer 9

.polarity (if it is polar it will dissolve, if non polar will not dissolve)
