What is the [OH-]if the pH of a solution 10.62

1 answer:

5 0

As we know,

pH + pOH = 14
Or,
pOH = 14 - pH

Putting Value of pH,

pOH = 14 - 10.62

pOH = 3.38

pOH is converted into [OH⁻] as follow,

[OH⁻] = 10⁻pOH ∴ -pOH is in power, 10 means antilog

[OH⁻] = 10⁻³°³⁸

[OH⁻] = 0.0004168

[OH⁻] = 4.16 × 10⁻⁴

Marianna [84]

After the dillution of the solution, the wavelength of maximum absorption is decreased.

<h3>What is the wavelength of maximum absorption?</h3>

The wavelength of maximum absorption is the wavelength at which the solution absorbs the maximum amount of light. It is usually shown as a hump in the spectrum.

When the starting concentration of the K2Cr2O7 is diluted, the wavelength of maxium absorption decreases.
