AI Thread Summary
The discussion revolves around determining the concentrations of Cl- and Ag+ in an aqueous solution of KCl after adding AgNO3. A galvanic cell setup was used to measure the emf after incremental additions of AgNO3. The participant suggests calculating the concentration of Ag+ based on the moles added and the total volume of the solution. They also mention calculating Cl- concentration using the remaining moles after the reaction. There is uncertainty about whether additional equations are needed for accurate calculations, indicating a potential lack of information.

Homework Statement


A is an aqueous solution of KCl(aq) with unknown concentration. The
following experiment was carried out at 25°C to determine the concentration
of Cl- (aq) in A, and the Ksp of AgCl(s)

Step 1: A half-cell was made by dipping a silver strip into 100.0 cm3
of A.

Step 2: A galvanic cell was constructed by connecting the half-cell made in
Step 1 to a standard Zn2+(aq)  Zn(s) half-cell with a suitable salt bridge.

Step 3: 0.100 M of AgNO3(aq) was added in portions from a burette to A. After
each addition of AgNO3(aq), the emf of the galvanic cell was measured.

When 8.0 cm3
of AgNO3(aq) had been added to A, what is the cell emf
(E) and the concentration of Ag+(aq) and Cl-
(aq) in the resultant solution?

The Attempt at a Solution


i just simply cal the [Ag+] added to the solution and by (mole added)/[total volume (108cm3)]
and [Cl-] by (mole remained after reaction)/[total volume(108cm3)]
is it correct? or need other specific equation to cal this 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...
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...
