Aspirin is acetylsalicylic
acid (ASA) (
C9H8O4). It reacts with NaOH ( a
base) to produce salt (sodium acetylate) and water. Both Aspirin
and NaOH react in 1:1 molar ratio, as
C9H8O4
+
NaOH →
NaC9H7O4
+ H2O
So, moles of NaOH = moles of ASA
Or, mmol of of NaOH = mmole of
ASA
; mmol is milli mol
and mmole of NaOH = Molarity of NaOH * Volume
of naOH used (in ml)
=
(0.1177 M) *...
