KCET2009ChemistryElectrochemistry
An aqueous solution containing 6.5 ~g of NaCl of 90 % purity was subjected to electrolysis. After the complete electrolysis, the solution was evaporated to get solid NaOH . The volume of 1 M acetic acid required to neutralise NaOH obtained above is
Options
- A1000 ~cm ³
- B2000 ~cm ³
- C100 ~cm ³
- D200 ~cm ³
Correct answer
C. 100 ~cm ³
Step-by-step solution
Weight of pure NaCl =6.5 0.9=5.85 ~g No. of equivalence of NaCl = 5.85 58.5 =0.1 No. of equivalence of NaOH obtained =0.1 Volume of 1 M acetic acid required for the neutralisation of NaOH = 0.1 1000 1 =100 ~cm ³
