Hi,

Suppose we have two 0.1M solutions in water. What is their conductivity and how will it change when we mix them, and why?

A) NaCl and KCl:

Okay, so both are strong electrolytes and conduct well but what happens when they get mixed and why?

B) CH3COOH and NH3*H2O:

Both are weak electrolytes and will conduct electricity. Again, I don't know what happens after mixing and why?

C) HCl and NaOH

Both strong electrolytes, they neutralize each other in a reaction. So, the result is no conductivity? (very weak)

Thank you for your answers.

Edit: I've come up with (maybe helpful) equations:
A) No reaction?

B) CH3COOH + NH3*H2O -> CH3COONH4 + H2O
Ions: CH3COO- + H+ -> CH3COO- + NH4+ + H2O,
We can reduce it to OH- + H+ -> H2O

C) NaOH + HCl -> NaCl + H2O
Same, when looking at ions we can reduce things to:
OH- + H+ -> H2O

What is responsible for conduction in the solution?

[Laboratorium3]

Ions.

[Borek]

Yes. Can you try to predict how the concentrations and amount of ions will change in each case?

[Laboratorium3]

A) Stronger conductivity, because there is more ions
B) They neutralize each other so weaker conductivity
C) They neutralize each other so weaker conductivity
