Calculation of Purity of Concentrated H2SO4 Solution
1. Given Data:
- Specific gravity of H2SO4 solution: 1.8 g/ml
- Volume of H2SO4 solution used: 5 ml
- Volume of 2N NaOH used for neutralization: 84.6 ml
2. Calculating Equivalent Weight of H2SO4:
- The normality of NaOH is 2N, which means it can neutralize 2 equivalents of acid.
- From the reaction: H2SO4 + 2NaOH → Na2SO4 + 2H2O
- 1 mole of H2SO4 reacts with 2 moles of NaOH
- Equivalent weight of H2SO4 = Molar mass of H2SO4 / 2
- Molar mass of H2SO4 = 2(1.008) + 32.06 + 4(16.00) = 98.08 g/mol
- Equivalent weight of H2SO4 = 98.08 / 2 = 49.04 g/equivalent
3. Calculating Normality of H2SO4 Solution:
- Normality of H2SO4 = Normality of NaOH * Volume of NaOH / Volume of H2SO4
- Normality of H2SO4 = 2 * 84.6 / 5 = 33.84N
4. Calculating the Purity of H2SO4 Solution:
- Purity of H2SO4 = (Equivalent weight of H2SO4 * Normality of H2SO4 * 100) / Specific gravity
- Purity of H2SO4 = (49.04 * 33.84 * 100) / 1.8 = 1620.27%
5. Conclusion:
- The purity of the concentrated H2SO4 solution is 1620.27%. This indicates that the solution is not pure and may contain impurities or water. Further purification steps may be required to obtain a higher purity level.
