AI Thread Summary
Contamination of Ba(OH)2 with lead (II) chloride would likely increase the calculated concentration due to the formation of insoluble lead compounds, affecting the titration results. The presence of FeCl3 could introduce additional reactions that alter the solution's composition, potentially leading to inaccurate concentration readings. The original composition of the solution changes with these contaminants, impacting the stoichiometry of the titration. Understanding the specific reactions that occur is crucial for accurate calculations. Overall, both contaminants would complicate the titration process and yield misleading concentration values.

Homework Statement



suppose a small amount lead (II) chloride got into your Ba(OH)2 sample before titration, contaminating it. how do you think the contamination would affect your calculated concentration for the sample? what about a small amount of FeCl3?

Homework Equations





The Attempt at a Solution


would it just make it less soluble and therefore make the calculated concentration too high? why?
 
Physics news on Phys.org
Think what reactions will occur after contaminant is added. How do they change the original composition of the solution? How these changes in the composition will be reflected in the final result of your titration?

Note: you have not told what kind of titration you are going to do, so whole thing doesn't make much sense.

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...
