Solution:
To solve this problem, we need to determine the concentration of Ca2+ ions in the blood sample based on the reaction between the blood sample and KMnO4.
1. Write the balanced chemical equation:
The reaction between calcium oxalate (CaC2O4) and KMnO4 can be represented by the following balanced chemical equation:
2MnO4- + 5C2O42- + 16H+ → 10CO2 + 2Mn2+ + 8H2O
From the balanced equation, we can see that 2 moles of KMnO4 react with 5 moles of calcium oxalate to produce 10 moles of CO2.
2. Calculate the moles of KMnO4 used:
Given that 20 mL of 0.001 M KMnO4 is used, we can calculate the moles of KMnO4 used using the formula:
moles = concentration × volume
moles = 0.001 M × 0.020 L
moles = 0.00002 mol
3. Determine the moles of calcium oxalate:
Since the reaction between KMnO4 and calcium oxalate is in a 1:5 ratio, we can determine the moles of calcium oxalate using the mole ratio:
moles of calcium oxalate = (moles of KMnO4) × (5/2)
moles of calcium oxalate = 0.00002 mol × (5/2)
moles of calcium oxalate = 0.00005 mol
4. Calculate the moles of Ca2+ ions:
From the balanced chemical equation, we can see that 5 moles of calcium oxalate produce 2 moles of Ca2+ ions.
moles of Ca2+ ions = (moles of calcium oxalate) × (2/5)
moles of Ca2+ ions = 0.00005 mol × (2/5)
moles of Ca2+ ions = 0.00002 mol
5. Determine the concentration of Ca2+ ions:
Finally, we need to determine the concentration of Ca2+ ions in the blood sample. Since the blood sample was dissolved in 10 mL of solution, we can calculate the concentration using the formula:
concentration = moles/volume
concentration = 0.00002 mol/0.010 L
concentration = 0.002 M
Therefore, the concentration of Ca2+ ions in the blood sample is 0.002 M.
To solve this problem, we need to determine the concentration of Ca2+ ions in the blood sample based on the reaction between the blood sample and KMnO4.

concentration = 0.002 M
Therefore, the concentration of Ca2+ ions in the blood sample is 0.002 M.
