3.3. To determine the concentration of HF, the dependence of the electrical conductivity æ on the acid content in the solution is used:
СHF, mol/l 0.004 0.007 0.015 0.030 0.060 0.121 0.243
æ *104, cm 2.5 3.8 5.0 8.0 12.3 21.0 36.3
Construct a calibration graph based on these data in the coordinates lg æ - lg CHF and use it to determine the concentration of hydrofluoric acid if its electrical conductivity is equal to:
10 option
æ *104, cm - 20.1
