What is the pH of a 0.250 M NH4Cl solution? Kb for NH3 = 1.8 × 10−5. Thank you.

the cell is written like that in the report sheet so that's why I wrote it like that

I have a question. For Fe|Fe^+2 (1M)| Cu|Cu^+2 (1M why did you use Fe^2+ ==> Fe^3+ + e Eo = -0.771 ? instead of: Fe ---> Fe^+2 + 2e ? thank you..

I'm adding this to my previous question..in our textbook its says Ecell=Ecathode-Eanode. That's my values were smaller. But you added them. Will that make a difference? Should I do it the way you did it? Because they have to be bigger numbers? Thank you.

the measured cell voltages are supposed to be smaller than the theoretical cell voltages, but when I'm calculating the theoretical cell voltages they are smaller. And I don't know why I'm getting these. Can you please check if I'm doing it right. Thank you. Mea...

Calculate the reduction potential of the following solutions: a- 1 M CuSO4 b- 1 M FeSO4 c- 0.1 M CuSO4 I'm now the same answer as you. :( This is how I did it can you please check. a- Cu(s)---> Cu(aq) + 2e = -0.34 V SO4^-2(aq) + 4H(aq) + 2e --> H2SO3(aq) + H2O(l)= 0....

Please help me I've been trying for the whole day!
chemistry
Please...how do you calculate the reduction potential for 1 M CuSO4? I've been trying for hours......!!
chemistry
Thank you very much..And I posted another question, the most important ones that I don't know how to do.
chemistry
******HOW DO YOU CALCULATE THE REDUCTION POTENTIAL OF 1 M CuSO4 AND 0.1 M CuSO4? NOTE: THE REDUCTION POTENTIAL OF 1M Zn(NO3)2 IS -0.76 V. I'M REALLY STUCK.
