Respuesta :
If the [OH⁻] of a solution is 2.7 × 10⁻⁴ mol/L the pOH of the solution is 3.569.
What is pH ?
pH is used to measure whether the substance is acidic, basic or neutral and the range is 0-14.
How to find the pOH of the solution ?
To calculate the pOH it is expressed as:
pOH = - log[OH⁻]
= - log[2.7 × 10⁻⁴]
= - [log 2.7 + log 10⁻⁴] [log a × b = log + log b]
= - [log 2.7 - 4 log 10] [log aˣ = x log a]
= - [log 2.7 - 4 × 1] [log 10 = 1]
= - [log 2.7 - 4]
= - [0.431 - 4]
= - [-3.569]
= 3.569
Thus, from above conclusion we can say that If the [OH⁻] of a solution is 2.7 × 10⁻⁴ mol/L the pOH of the solution is 3.569.
