\(0.1\) M aqueous solution of the following salts were prepared. Their conductivity values were measured at \(25\circ C\). Which of the following will possess least conductivity at \(25\circ C\)?
- A \(MgCl_2\)
- B \(BeCl_2\)
- C \(SrCl_2\)
- D \(CaCl_2\)
Answer & Solution
Correct Answer
(B) \(BeCl_2\)
Step-by-step Solution
Detailed explanation
Ionic mobility depends on hydrated ionic radius. Smaller bare ions hydrate more extensively, leading to larger hydrated radii and lower mobility. Order of bare ionic radii: \(Be^{2+} Order of hydration:…
