The hydronium ion concentration of the solution with given value of pOH is 7.94 × 10⁻⁸M.

Option D) is the correct answer.

<h3>What is pH of solution?</h3>

The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration  [H+] of the given solution.

From the formular;

pH = -log[ H⁺ ]

pH + pOH = 14

Given that;

  • pOH =  6.90
  • Hydronium ion concentration OH⁻ = ?

First we find the pH

pH + pOH = 14

pH + 6.90 = 14

pH = 14 - 6.90

pH = 7.1

Now, from the above expression;

pH = -log[ H⁺ ]

Hence;

[ H⁺] = 10^(-pH)

[ H⁺] = 10^(-7.1)

[ H⁺] = 7.94 × 10⁻⁸M

Therefore, the hydronium ion concentration of the solution with given value of pOH is 7.94 × 10⁻⁸M.

Option D) is the correct answer.

How do ethical concerns affect scientific research?
VARVARA [1.3K]
Hello

We can approach science from various angles. It may be that our aim is to solve a problem or to try to understand something. But, at the same time, what we find in it as explanatory or credible may be different if our profession is to be a trader, an importer of industrial equipment, a researcher or a teacher. Our concerns about science may differ according to the angle from which we think about it. That is to say, what is important when judging or evaluating science is different according to our relationship with it at certain times: whether we see it as producers, disseminators or consumers. Therefore, from the outset we have an area of complexity in thinking about science from our starting point.

Why is health insurance so appealing to people?
Shtirlitz [24]

Answer:

Having medical coverage is significant for a few reasons. Uninsured individuals get less clinical consideration and less opportune consideration, they have more regrettable wellbeing results, and absence of protection is a monetary weight for them and their families. In addition, the advantages of extending inclusion exceed the expenses for included administrations. Wellbeing net consideration from emergency clinics and centers improves access to mind yet doesn't completely fill in for medical coverage. These discoveries are upheld by much research, albeit a few alerts are suitable in utilizing these outcomes.
