Unformatted text preview: 4. What type of solution do you think will conduct more electricity-an ionic or molecular solution? The ionic solutions will conduct more electricity because they are composed of water and water is a good conductant. 5. What type of positive control do you think would be needed in today’s experiment and are we using one? The positive control needed in our lab is a type of water so all the compounds will be exposed to the same kind of solution. Our control in this lab is distilled water....
