How to evaluate the conductivity of a solution

What does it mean if an acid or base conducts electricity strongly?

• It is considered a weak acid or base

• It is considered a strong acid or base

• It is called a non-electrolyte

• It means it cannot dissolve in water

Which of the following is an example of a strong acid?

• Sucrose

• Acetic acid

• Sodium chloride

• Hydrochloric acid (HCl)

What type of solution does not support a current?

• Electrolyte

• Saturated solution

• Supersaturated solution

• Non-electrolyte

What happens when solid NaCl dissolves in water?

• The solution becomes a non-electrolyte

• The light bulb does not light up

• The solution lights up the bulb brightly

• The solution fails to light the bulb

Which of the following is a weak electrolyte?

• 1M acetic acid solution

• Deionized water

• Solid granular sucrose

• Solid granular sodium chloride

What affects the conductivity of an electrolyte?

• The concentration of ions in solution

• The brand of conductivity tester used

• The size of the container

• The color of the solution

What is a supersaturated solution?

• A solution that does not dissolve any solute

• A solution that contains more solute than it can normally dissolve

• A solution that contains the maximum amount of solute it can dissolve

• A solution that contains less solute than it can normally dissolve

What factor does NOT affect the rate of dissolution?

• The color of the solute

• The temperature of the solvent

• The surface area of the solute

• The amount of agitation

What indicates that a solution is an electrolyte?

• It turns into a solid when electricity is applied

• It does not support a current

• It supports a current

• It changes color when electricity is applied
