    Cell Travel
AI Thread Summary
In a voltaic cell, cations from the salt bridge migrate towards the cathode, not the anode, which is negatively charged. The anode experiences oxidation, leading to a loss of mass, while the cathode gains mass due to reduction. The salt bridge serves to maintain electrical neutrality by allowing ions to flow, balancing the charge as the reaction proceeds. Understanding the movement of ions is crucial for grasping the overall function of a voltaic cell. This clarification highlights the essential roles of both the anode and cathode in electrochemical reactions.

Homework Statement


A voltaic cell is set up and a chemical reaction proceeds spontaneously. Which of the following will not occur in this reaction?
(A) The electrons will migrate through the wire.
(B) The cations in the salt bridge will migrate to the anode half cell.
(C) The cathode will gain mass.
(D) The anode will lose mass.
(E) Reduction will occur at the cathode.

The Attempt at a Solution


The anode is negatively charged so I thought cations will travel to the anode but apparently this is not true. Can someone clarify this?

Thanks!

What happens at the anode half cell?
They mention the cations in the salt bridge
So what is the use of a salt bridge?

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...
