Hello, my name is margaret, and today i'm going to be helping you with zoomdahl chapter 18, electrochemistry, problem number nine.
00:11
And for a quick recap of the problem, it says you were told that metal a is a better reducing agent than metal b.
00:19
What, if anything, can be said about the positive aion and the positive b ion, explain.
00:27
So let's really quickly look at what the electrochemical reactions for a and a plus and b plus would look like.
00:45
So starting out with a, we have writing them in reduction form because that's the best way to keep yourself.
00:58
From not being confused with all the equations and everything.
01:03
So we have a plus plus an electron goes to a as a metal, which is a solid.
01:16
And then we have b as an ion plus an electron goes to b as a solid.
01:25
And going back to the problem, it says that metal a is a better reducing agent than metal b.
01:36
So what it's saying is that a is the better reducing...
