Determining Fe2+ Concentration by Redox Titration

AI Thread Summary
Iron(II) can be quantified through redox titration using a cerium(IV) solution, where the reaction involves the conversion of Fe2+ to Fe3+ and Ce4+ to Ce3+. To find the concentration of Fe2+, a 10.00 mL aliquot of the sample requires 21.35 mL of 0.3136 M Ce4+ for titration to the endpoint. The calculation involves determining the moles of Ce4+ used and relating it to the moles of Fe2+ in the aliquot. Participants are encouraged to show their calculation attempts to receive assistance, adhering to forum policy. This method provides a reliable means of determining Fe2+ concentration in solutions.

iron(ii) can be determined by redox titration with a cerium (iv) solution. the oxidation reduced reaction is fe2+ + ce2+ = fe3+ + ce3+

what is the concentration of fe2+ if it requires 21.35mL of .3136 ce4+ to titrate a 10.00mL aliquot to the endpoint.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
