I have 1.01 of a solution that is 0.100M Fe(NO3)2 and 0.200M Cu(NO3)2. I want to seperate the metal ions. I gradually add a solution that is 0.100M in K3PO4, 0.100 M in KOH, and 0.100 M in K2CO3.What volume of the solution do I need to add to get the first metal to begin to precipitate?

c) Fe/0.1 M FeSO4//0.1 M CuSO4/Cu
I soaked a porous cup in tap water for a few minutes and then i
let it stand in a 100 ml beaker containing 10ml of 0.1 M FeSO4. I
added enough 0.1M CuSO4 to the cup until the two liquid levels were
the same height. I inserted a zinc strip into the 0.1 M FeSO4 and a
shiny copper strip into the 0.1 M CuSO4. I connected the...

You have 315 mL of an aqueous solution that is 0.29 M Na2SO4 and a separate 250 mL aqueous solution that is 0.41 M BaCl2- a). How many moles of each of the four ions are present (do not use the word "moles" in your answer, just the number)? Na+ 5042- Ba2+ ci b). When these two solutions are mixed together, what is the chemical formula of the solid expected to precipitate from the mixture? (Don't forget to put (s)...

how do these things affect eachother? if I have Zn(s)|Zn2+(aq)||Ag+(aq)|Ag(s) and the solution in the salt bridge is changes to CH3OH from potassium nitrate. if I have Fe3+(aq)|Fe2+(aq)||Ag+(aq)|Ag(s) and the iron (ii) nitrate solution is replaced with salt water if I have Cu(s)|Cu2+(aq)||MnO4^-(aq)|C(s) and I replaced the carbon electrode with silver the rest are voltaic cells if I have Co (s) | Co2+ (aq)|| Cu2+(aq) |Cu (s) instead of a porous cup we turn it into two half cells connected...

I have various sums that I've calculated from my dataframe and I want to use matplotlib and make pi chart of percentage of students with a particular nationality. for ex, totalStudents=(df.sum()) studentsSwiss=(df1.sum()) studentsIndian=(df2.sum()) studentsChinese=(df3.sum()) etc. And I want the pi chart to be in percentage. so take in those values convert to percentage of total students of that nationality. I'm using python. additional info: df is a dataframe that has a column that sums total Swiss, Indian, Chinese nationalities and...

Hi,
can anyone please help me with this? i have no clue how to define
if a reaction is Oxidation reduction or not. Thanks a lot
OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
