What is the pH of a solution when the [OH - ] = 1 x 10 -3

Chemistry

dsp733 years ago
8 0

Answer:

The pH is 11

Explanation:

Because pH + pOH = 14

and pOH = - log [OH⁻] = - log (1 x 10⁻³) = 3

we can now calculate pH by manipulating equation one above

pH = 14 - pOH = 14 - 3 = 11

Thus the pH of the solution is 11

Which of the following is not among the advantages of generating nuclear energy?
WARRIOR [948]

B

While nuclear energy does not pollute the environment, it poses the risk of radiation which is harmful to organisms because it causes lethal mutations.

Explanation:

Nuclear fission, for example, releases neutrons and other particles (at very high speeds) that can ionize materials including DNA. This will induce mutations of DNA most of which are usually lethal to organisms. Gamma and X- rays are also produced by fusion reactions and  if exposed to organisms also cause mutations on DNA through double stranded breaks. Therefore, the risk of an accident of a nuclear reactor can have immense ramifications on the ecosystems.

Is anyone good at chemistry if so can someone help me please ?
saveliy_v [14]

We're given the [OH⁻] as 8.34 × 10⁻¹² M. Using the formula pOH = -log[OH⁻], the pOH of this solution would be -log(8.34 × 10⁻¹²) ≈ 11.08.

The pOH is, for lack of a better term, the "opposite" of pH: A pOH of 7 is neutral; a pOH less than 7 is <em>basic</em>; and a pOH greater than 7 is <em>acidic</em>.

This follows from the relation, pH + pOH = 14. In this case, with a pOH of 11.08, our pH would be 14 - 11.08 = 2.92, which is acidic (pH < 7).

Thus, the correct answer choice is B.
