I have a TA test kit that uses sodium hydroxide 0.2N as a reagent. I need more of it, and all I can find is 0.1N. Anybody know the difference, or where I can find 0.2N?
(I'm an EE, not a chemist)
Thanks

+1I'm an EE too, but I attempt chemistry on TV. You'll get more accurate results using the 0.1N formulation since you can more easily measure a larger volume. You just end up using twice as much.
0.2N means 0.2 molar concentration. Since NaOH is 40g/mole, this means you can make your own soln with 8g per liter of distilled water. I buy NaOH from Amazon and make my own soln.
@jgmillr1 Do you know the shelf stability of solid NaOH? I think the solution is only good for 6-12 months.
