Why is HC2H3O2 not a good conductor or strong electrolyte?
For the microscale titration between KMnO4 and H2O2 the balanced net ionic equation is 2 MnO4-(aq) + 5 H2O2(aq) + 6 H+(aq) --> 2 Mn2+(aq) + 5 O2(g) + 8 H2O(l)
Aspirin (C9H8O4) is produced through the following reaction of salicylic acid (C7H6O3) and acetic anhydride (C4H6O3). C7H6O3(s) + C4H6O3-> C9H8O4(s) + HC2H3O2
