Question:
એસિડિક માધ્યમમાં, 0.25 M ઓક્ઝેલિક એસિડના 10 mL ને KMnO₄ દ્રાવણ સાથે ટાઇટ્રેટ કરવામાં આવે છે. જો અંતિમ બિંદુ માટે KMnO₄ નું જરૂરી વોલ્યુમ 10 mL હોય, તો KMnO₄ દ્રાવણની શક્તિ છે:

The Correct Option is
B
Solution and Explanation
Step 1: Understanding the Concept:
પ્રતિક્રિયા: \( 2KMnO_4 + 5H_2C_2O_4 + 3H_2SO_4 \rightarrow K_2SO_4 + 2MnSO_4 + 10CO_2 + 8H_2O \).
Step 2: Key Formula or Approach:
તુલ્યતાના સિદ્ધાંત મુજબ: \( n_1 M_1 V_1 = n_2 M_2 V_2 \).
- ઓક્ઝેલિક એસિડ માટે n-ફેક્ટર = 2.
- KMnO₄ (એસિડિક માધ્યમમાં) માટે n-ફેક્ટર = 5.
Step 3: Detailed Explanation:
- \( 5 \times M_{KMnO_4} \times 10 = 2 \times 0.25 \times 10 \).
- \( 5 \times M_{KMnO_4} = 0.50 \).
- \( M_{KMnO_4} = 0.10 \) M.
Step 4: Final Answer:
KMnO₄ દ્રાવણની શક્તિ 0.10 M છે.
