I am trying to make a 0.0667N NAOH solution for titration to find TA.
I have .2N NAOH solution for going the phenolpthalein route but don't
like using that technique because of inaccuracy. I want to use pH
meter to find end point. I know the grams/liter of NAOH needed to
make the solution but would have to buy the NAOH from chem supply.
One supplier wanted $23.50 for 200 grams of lab quality NAOH and on
top of that wanted $37.50 to ship it! Forget that! All I want to
know is how many milliliters of distilled/deionized water I need to
add to the .2N NAOH solution to make it a 0.0667N NAOH solution.
Anyone?
