What is the best description for a solution with a hydroxide-ion concentration equal to 1 x 10-4 m?

This is a basic solution

Explanation:

To be able to provide a succint description of this solution, from the given parameters we can deduce the pH of the solution.

Given parameters:

Concentration of OH⁻ = 1 x 10⁻⁴M

Solution

          We knonw that pOH = -log₁₀[OH⁻]

                   pOH = -log₁₀ 0.0001 = - (-4) = 4

For an aqeous solution:

                  pH + pOH = 14

                  pH = 14 - 4 = 10

The pH of the solution has been derieved to be 10

This is a basic solution

i believe it is 40–40–20%

explanation:

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
