Question

if a student wants to perform a standardization of a NaOH solution, what is the best method to accomplish this and why is it the best method?

Answer 1

standardization is essentially just a titration, executed plenty of time in order to get a correct vlaue of the normality/molarity of the solution

The best method to neutralize NaOh, is useing HCl, Hydrochloric acid

try to use similar volumes (i.e. 50 ml vs 50 ml approx) and change concnetrations ( in the order of decimals i.e. 0.1, 0.20, etc..)

then apply titration, neutralize, use pH indicator such a phenolphtalein and do calculations

mol of base = mol of acid

according to:

NaOh + Hcl = H2O + NaCl

then

M = mol/V
