Question

1. Which of the following compounds, based upon their chemical formulas, would you expect to show no conductivity?

2. Solution A, an aqueous ionic solution which contains one cation and one anion, shows a conductivity reading of 7000 microsiemens/cm. Solution B, an aqueous ionic solution containing an unknown number of cations and anions, shows a conductivity reading of 12000 microsiemens/cm. What can you say about the relative number of ions in the Solution B as compared to Solution A? Explain your reasoning.

Explanation / Answer

C2H5O , SF2 , SO3 . because these are molecular compounds.

2. By increasing concentration , conductivity decreases. so that

the No of ions in solution B is lesser than solution A.
