Question

The specific conductance of saturated solution of
CaF, is 3.86 x 10-5 mho cm-1 and that of water
used for solution is 0.15 x 10-5. The specific
conductance of CaF, alone is
(1) 3.71 x 10-5
(2) 4.01 × 10-5
(3) 3.7 ×104
(4) 3.86 x 10-4​

Answer 1

Answer:

The specific conductance of saturated solution = specific conductance of caF2 + specific conductance of water.

Explanation:

Given that ,

specific conductance of saturated solution = 3.8610^-5.

and specific conductance of water = 0.15×10^-5

therefore , specific conductance of caF2 alone is = [3.86×10^-5] - [0.15×10^-5]

= [3.71×10-5]
