Product Description
1. To determine the concentration of HF, use the dependence of the specific conductivity (ϰo) on the acid content (C) in the solution:
C, mol/l 0.004 0.007 0.015 0.030 0.060 0.121 0.243
ϰo ⋅104 , Ohm−1 ⋅ cm−1 2.5 3.8 5.0 8.0 12.3 21.0 36.3
Plot a calibration graph lgϰo= f (lgC) based on this data and use it to determine the concentration of HF if the specific conductivity of the solution is:
Option No. 1
ϰo ⋅104 , Ohm−1⋅cm−1 3.2
