This question asks us what generalizations we can make about substances that can dissolve in water and conduct electricity once they have dissolved.
00:19
Some of the examples for substances like that are sodium chloride, calcium chloride, copper sulfate.
00:43
So what all of these have in common is that once they dissolve in water, they form ions.
00:53
So sodium will form a metallic ion.
00:57
We say it's in the aqueous form and then it will form chloride anions.
01:06
So it will form a sodium cation and a chloride anion.
01:11
Calcium chloride will form a calcium cation in the acous media and two chloride anions.
01:26
I'm sorry, there's no two here.
01:29
The two has to be in front of chlorine.
01:33
And copper sulfate will form copper catalyons, which have a 2 plus charge, because they have lost two electrons and sulfate 2 minus anions...
