This question asks us to write the balanced formula equation for the acid -based reaction that occurs when the following are mixed.
00:08
Here are all of those reactions, and because it tells us their acid -based reactions, we know that one of the products is going to be water.
00:14
So i've already written that out for each of these.
00:16
Now let's figure out what the other compound that's formed is.
00:19
In the first reaction, we have potassium hydroxide, aqueous, mixing with nitric acid.
00:26
And so the cation here is potassium.
00:28
The anion here is nitrate, so we are going to form potassium nitrate.
00:35
That is highly soluble.
00:40
Now we just have to balance.
00:42
One potassium on both sides.
00:48
Four oxygens on this side.
00:52
I'm sorry, there's four oxygens on both sides.
00:54
One nitrogen on both sides...
