Calculate the molarity of sodium hydroxide in the diluted drain cleaner sample
Sodium hydroxide (NaOH) is the active ingredient in drain cleaners.
In an experiment to determine the concentration of sodium hydroxide
in a drain cleaner sample, 25 cm3
of the sample was diluted with
water to 250 cm3
. 10 cm3
of the diluted sample required 16.3 cm3
0.14 M sulphuric acid (H2SO4) for complete neutralization.
Given: 2NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + 2H2O(l)
