Worksheet: Electrolytes

In this worksheet, we will practice defining an electrolyte and explaining how dissolved ions interact with a solvent and increase electrical conductivity.

Q1:

If all of the following solutions were of the same concentration, which would have the highest electrical conductivity?

  • A N H ( ) 3 a q
  • B N a O H ( ) a q
  • C G l u c o s e ( ) a q
  • D B r ( ) 2 a q
  • E C H C O O H ( ) 3 a q

Q2:

Which of the following, if added to the same quantity of water, would produce a solution with the highest conductivity?

  • A 5 g N a C l
  • B 5 g K S O 2 4
  • C 5 g K N O 3
  • D 5 g N a C O 2 3
  • E 5 g L i B r
