B. 1.6×10−9M1.6 \times {10}^{- 9}M

Step-by-step solution

The solubility of AgCl (s) with solubility product 1.6 × 10 ^ - 10 in 0.1MNaCl solution would be

The phenomenon in which the addition of an ion common to two solutes causes precipitation or reduces ionization is known as common ion effect.

∴Ksp(AgCl)=S(S+0.1)∴ {K}_{sp\left(AgCl\right)} = S\left(S + 0.1\right)

∵S≪0.1∵ S ≪ 0.1

∴S+0.1≈0.1∴ S + 0.1 \approx 0.1

∴1.6×10−10=S×0.1∴ 1.6 \times {10}^{- 10} = S \times 0.1

∴S=1.6×10−9M∴ S = 1.6 \times {10}^{- 9}M
