1.

Which one of the following solution will have highest conductivity .

Answer»

`0.1 M CH_(3) COOH`
`0.1 M NaCl`
`0.1 M KNO_(3)`
`0.1 M HCl`

Solution :NaCl, `KNO_(3) , HCl` are strong ELECTROLYTES but the SIZE of `H^(+)` is smallest . Smaller size of the ions , greater is the CONDUCTANCE and hence greateris the conductivity ( k = `G XX` cell const.)
