1. Electrical current is carried by a flow of charged particles, which often occurs through electrons in metal or ions in solution. This flow can only happen in an aqueous solution if whole (not partial) charges are present. Based on this information, a. does tap water conduct electricity? Consider whether there are enough charges for ions to flow in a solution of tap water. b. does pure water conduct electricity? Consider whether there are enough charges for ions to flow in a solution of pure water.

In chemistry lab, Sam are given a sample of a salt water solution. He measure its electrical conductivity. He then pour the salt water through a purification filter. If he measure the purified water’s electrical conductivity, do he expect it to be lower or higher than the unfiltered water, and why? A Higher: purifying water removes ions from the water allowing it to carry more current. B Higher: purifying water increases the number ions in the water allowing it to carry more current. C Lower: purifying water removes ions from the water causing it to carry less current. D Lower: purifying water increases the number of ions in the water causing it to carry less current.
