An extraction procedure specifies that an aqueous solution containing dissolved organic material be extracted twice with 10-ml portions of diethyl ether. a student removes the lower layer after the first extraction and adds the second 10-ml portion of ether to the upper layer remaining in the separatory funnel. after shaking the funnel, the student observes only one liquid phase with no interface. explain.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

what is the question?

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

you need to have a picture of the atom that way we can answer it
