Testing NaOH purity?
« on: April 05, 2004, 12:51:41 PM »
Is there an easy way to test 50%NaOH for purity?

If its 50% NaOH don't you already know its purity?

LOL!  I am asking bc in a lab experiment we used what was thought to be 50% NaOH but it was found not to be bc nobody's experiement worked except for those that it took it straight out of the NaOH bottle.

Just do a titration. And I don't want to hear any complaining, I had to do an air sensitive titration, and I did it under an hour it's no big deal. :P
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
