Hi guys, would greatly appreciate it if you could help me with these calculations
please
lab session: determination of the decossiation constant of acetic acid by conductivity.
questions: 1; calculate the cell constant 2; correct all your readings for the cell constant and the conductivity of water 3; determine Λm° using graphycal method, 4; for each solution determine a and hence k.
this is the data from lab:
Solution : Conductivity µS cm-1Standrad KCl : 2.69
Mili-q water : 6.90
0.1M acetic acid : 491
0.05M acetic acid : 343
0.025M acetic acid : 246
0.010M acetic acid : 152.8
0.005M acetic acid : 106.6
0.0025M acetic acid : 75.8
0.0010M acetic acid : 48.5
morality of the standard KCl= 2.777 mS cm-1i belive Cell constant = Molarity of standard KCl / Measured average conductivity of KCl (mS).. does that sound right ?
i literally have no idea how to go on about most of it tho i have some undrstanding please help if you can.
thank you very much in advance. really great-full for any help you can put in.
