What do you have copied?


Sodium hydroxide tends to absorb water from the air, so when you weigh it out, what you weigh won't all be NaOH - there will be an unknown amount of water in the sample. Since there's no way of knowing how much water is in the NaOH you weigh out, there's also no way of knowing how much NaOH there is. When you make the solution, you won't know accurately how many moles of NaOH are present, so you have to find that out from a titration with an accurately known amount of an acid like potassium hydrogen phthalate (KHP): i.e. you have to standardize the NaOH solution.
