Discussion
1. Which of the solutions was able to conduct electricity?
Sodium Chloride, Magnesium Chloride and Sodium Bicarbonate

They both have Chlorine in it
3. Suggest why it is important that the sugar and bicarbonate solutions were prepared
using distilled water rather then tap water?
It is important because the tap water might have impurities in it.

Yes it would because when we mixed sodium chloride it conducted electricity and sea
water is the same so yes it conducts.
