hi! i would just like to ask if anyone could help me with the procedure on how to determine the concentration of sodium hydroxide? we have an existing...
You can eliminate the use of indicators altogether if you use an accurate pH meter. You will need a set of buffers to set up the Ph meter though. I assuming...
Hiya, Sofia! In my experience, the best way to standardize a NaOH solution is by titrating against a standard of oven-dried potassium hydrogen phthalate. As...

i think i misstated my query. steve, what i want to get is the purity of the NaOH sample, and not the molarity. but thanks for the help anyway! muah! ... ...
... purity is simply the concentration divided by the mass. take a sample of NaOH, determine the concentration and divide by the original weight. for example,...
