All right, so we're titrating an acid, h -c -l -o -4, and a base, which is n -a -o -h.
00:08
So when they react together, when you react an acid in a base, you always get water and a salt.
00:15
Salt comes from the cat -ion of the base and the anion of the acid, so n -a -c -l -o -4.
00:21
We have a monoproduct acid reacting with a base in a one -to -one ratio, so everything is balanced with coefficients of 1 in this equation.
00:32
Now we also want to know the number of moles of water form.
00:35
What's the yield? so we have 50 milliliters of 2 -molar h -c -l -o -4 reacting with 50 milliliters of 2 -molar n -o -h.
00:49
If you multiply, basically this, we can just change to liters.
00:54
Instead of 50 milliliters, we say that it's 0 .050 -0 liters.
01:00
And same thing here, but i won't change it twice because it's the same number.
01:05
Just divide by a thousand...
