Now, by the way, if you're confused at this part, or if you're confused about the autoimization of water, check out the link below. So we basically take our numbers, we plug them in, and we find that 10th of the negative 14 divided by seven gives you 1.43 times ten to negative 15 molar of this guy of seven molar nitric acid solution. So this means that our concentration of our base, of our hydroxide is very, very small. And this means this must be a very strong acid or a very acidic solution. So let's do part two, part B in this section. So, our sodium hydroxide dissociates into sodium and hydroxide.
