Question 8

Which of the following correctly describes dissolution?

Accepted Answer

The process of dissolving

Answer

The degradation of solution into smaller compounds

Answer

The process of a solution evaporating away

Question 9

Which of the following factors will NOT increase the rate of dissolution?

Accepted Answer

Decreasing the temperature

Answer

Increasing the surface area of the solute

Answer

Stirring the solution

Answer

Increasing the temperature

Question 10

Why do heating and stirring/agitation cause solutes to dissolve faster in a solution?

Accepted Answer

They increase the kinetic energy of the particles, allowing them to spread out more quickly

Answer

They decrease the kinetic energy of the particles, allowing them to move more quickly

Answer

They do not allow solute to dissolve faster

Question 11

Why does increasing the surface area of the solute (e.g. crushing it up) cause it to dissolve faster?

Accepted Answer

More of the particles are available of the surface to separate from one another and spread throughout the solvent

Answer

Small particles have less energy than big particles

Answer

Crushing the solute will cause it to dissolve slower not faster

Question 12

Which of the following accurately defines agitation (in reference to solutions)?

Accepted Answer

Stirring

Answer

Annoying

Answer

Bothering

Answer

Heating up

Question 13

What type of compounds conduct electricity when dissolved in a solution?

Accepted Answer

Ionic compounds

Answer

Covalent compounds

Question 14

What is the relationship between the concentration of an ionic compound (e.g. salt) and strength of electrical conductivity?

Accepted Answer

The higher the concentration the stronger the electrical conductivity

Answer

The higher the concentration the less electrical conductivity

Answer

Concentration does not affect electrical conductivity

Question 15

Does sugar conduct electricity when dissolved in solution?

Accepted Answer
