Calculate the pOH of a solution if the concentration of hydroxide ions (OH-) is 1.9 x 10-5M?

Chemistry

OLEGan [10]3 years ago

Answer:

9.28

Explanation:

pOH refers to a measure of hydroxide ions concentration. pOH tells about the alkalinity of a solution. If pOH is less than 7 then aqueous solutions are alkaline, acidic if pOH is greater than 7 and neutral if pOH is equal to 7.

Concentration of the hydroxide ions = 1.9 x 10-5 M

pH = -log(1.9\times 10^{-5})=4.72

pOH = 14 - pH

=14 - 4.72 = 9.28

An astronomer is a guest speaker at your school. She states that iron is the very last product in stellar fusion. Why would she
Zarrin [17]

Iron is the very last product in stellar fusion is that; Iron has a tightly bound nucleus, and atoms larger than iron are less stable and tend to undergo nuclear fission.

The stability of an atom is dependent on the binding energy per nucleon of the atom.

The binding energy per nucleon of elements increases steadily until iron, we can see that from the curve very easily.

Beyond iron, we have exceeded the region of stable binding energy per nucleon of atoms. The atoms after iron in the curve are mostly unstable heavy nuclei.

What makes the shadow during a solar eclipse
Damm [24]
Well, if you have a light bulb (turned on) n u put a little gulf ball in front of it it will make a shadow.
