If the molar concentration of is mol then the concentration of iodide ions of io

If the molar concentration of \( \boldsymbol{P b I}_{2} \) is \( 1.5 \times 10^{-3} \) mol \( L^{-1}, \) then the concentration of iodide ions of \( g \) ion \( L^{-1} \) is ?

  • A. \( 3.0 \times 10^{-3} \)
  • B. \( 6.0 \times 10^{-3} \)
  • C. \( 0.3 \times 10^{-3} \)
  • D. \( 0.6 \times 10^{-6} \)

Step-by-step solution

PbI2 dissociates completely into Pb²⁺ and 2I⁻. Thus, for 1 mole of PbI2, 2 moles of I⁻ are produced. Given [PbI2] = 1.5 × 10^{-3} M, [I⁻] = 2 × (1.5 × 10^{-3}) = 3.0 × 10^{-3} M.
