Among the aqueous solutions tested, which ones were strong electrolytes and which ones were weak? 6. 7.Explanation / Answer
Answer-1....
During the conductivity test the following procedure was followed:-
a) All the glass apparatuses were washed & rinsed thoroughly.
b) The analyte solution was prepared using volumetric flasks.
c) Conductometre was calibrated with the help of a buffer solution. And the electrodes were cleaned.
d) Analyte solution was taken into a beaker and electrodes were fixed in the beaker with the help of a stand.
e) conductivity readings were taken after each addition of 0.2ml of the base with a burette.
After every conductivity test the electrode must be washed and wiped properly and should be placed into the buffer solution
