The volume (in mL) of 0.1 M AgNO3required for complex precipitation of...
Given:
- Volume of [Cr(H2O)5Cl]Cl2 solution = 30 mL
- Concentration [Cr(H2O)5Cl]Cl2 solution = 0.01 M
- Concentration of AgNO3 solution = 0.1 M
To precipitate chloride ions present in the [Cr(H2O)5Cl]Cl2 solution, we need to add AgNO3 solution, which will react with chloride ions to form silver chloride precipitate.
The balanced chemical equation for the reaction is:
AgNO3 + NaCl → AgCl + NaNO3
From the equation, we can see that 1 mole of AgNO3 will react with 1 mole of NaCl (or chloride ions) to form 1 mole of AgCl.
To determine the volume of AgNO3 solution required for precipitation, we need to calculate the number of moles of chloride ions in the [Cr(H2O)5Cl]Cl2 solution:
Number of moles of [Cr(H2O)5Cl]Cl2 = concentration x volume = 0.01 x 0.03 = 0.0003 moles
Number of moles of Cl- ions = 0.0003 x 2 = 0.0006 moles (since there are 2 chloride ions per molecule of [Cr(H2O)5Cl]Cl2)
Now, we can calculate the number of moles of AgNO3 required to react with the chloride ions:
Number of moles of AgNO3 = number of moles of Cl- ions = 0.0006 moles
Finally, we can calculate the volume of AgNO3 solution required using the concentration:
Volume of AgNO3 = number of moles / concentration = 0.0006 / 0.1 = 0.006 L = 6 mL
Therefore, the correct option is (d) 6 mL.
