Identify each of these statements as true or false.
00:05
I'm going to pick a bright, bright color here.
00:10
How about this pink? and i'm going to give a t for those that are true.
00:13
So our first statement, a net ion equation shows only those ions that undergo chemical reaction.
00:23
And that is true.
00:26
And no spectators.
00:36
Number two, in a net ionic equation, the number of moles, of starting material must equal the number of moles of product.
00:47
And that is false.
00:50
As a simple one, let's do ag.
00:58
Simple example, 2 plus, excuse me, ag1 plus plus cl 1 minus yields agcl.
01:14
Both of these are aq.
01:17
We can see that we have two moles on the reactant side and one more on the product side.
01:25
Next, a net ionic equation must be balanced for both mass and charge.
01:34
So i'm going to say this is true because the solid, i'm going to go back to this one right here, this is a one plus and this is a one minus.
01:55
So they do cancel out.
01:59
Next, as a generalization, all lithium, sodium, and potassium salts are soluble.
02:04
And yes, that is true as a generalization.
02:08
It's not always true, but it's pretty true.
02:12
Next, as a general statement, all nitrate salts are soluble.
02:15
That is also true.
02:18
As a general statement, most carbonate salts are insoluble.
02:23
This is different because i don't really, i don't have the same.
02:28
Let me go see if i can find my solubility.
02:34
I've got a solubility table open somewhere here.
02:40
There it is...
