Re: Standardizing NaOH and HCL

I would look into standardization with KHP then. Basically yuou bake
the kHP in a warm oven to dry it out. Weigh it out, take it up into
solution and titrate it with your NaOH solution. Then you can
calculate your NaOH concentration. It is a proceedure used in college
chemistry classes so you should be able to find the exact proceedure on
google.

The problem is your 1 N NaOH solution will go bad just as easily as
your 0.1 N solution. As far as water to use, deionized water should be
fine but you have to degas it before use. To degas all you need to do
is boil the water for 5-10 min. Alternately you can vacuum degas it.
You have to do that to get rid of any CO2 dissolved in the water. (the
CO2 is what degrades NaOH, they combine to form bicarbonates).
