a solution has a poh of 4.75 at 50∘c. what is the ph of the solution given that kw=2.35×10−14 at this temperature?

Answer :

In other words, pH equals the negative log of the KW value given at 2.35 times 10 to the negative 14 -30H given at 4.75°C temprature. We also obtain 888.

What is pH?

The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7. In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

Why is pH so crucial?

A solution's pH is a significant indicator of its chemical composition. The pH can affect how readily available nutrients are, how biological processes work, how bacteria behave, and how chemicals behave.

If Kw = [H⁺][OH⁻] = 2.5 x 10⁻¹⁴, then

log₁₀ [H⁺] + log₁₀ [OH⁻] = log₁₀ (2.5 x 10⁻¹⁴), or

-log₁₀ [H⁺] - log₁₀ [OH⁻] = -log₁₀ (2.5 x 10⁻¹⁴), which is

pH + pOH = -log₁₀ (2.5 x 10⁻¹⁴) = 13.60
