Answer:

pH = 9.4

Explanation:

With the<em> given molarity of OH⁻ species</em> we can <u>calculate the pOH of the solution</u>:

pOH = -log[OH⁻]

pOH = 2.6

Now we can <em>use the pOH</em> to <u>calculate the pH of the solution</u>, with the following formula:

pH = 14 - pOH

pH = 14 - 2.6

pH = 9.4

So a solution containing a OH⁻ concentration of 0.0025 M has a pH of 9.4.

What is the energy stored in the bonds between Adams
Simora [160]
CHEMICAL ENERGY

Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy.

Chemical energy is the energy of chemical substances that is released when they undergo a chemical reaction and transform into other substances. Some examples of storage media of chemical energy include batteries, food, gasoline, and oxygen gas.
