The pH of the solution is B. 11.7.
What is pH value?
pH is a measure of hydrogen ion concentration, it is a measure of the acidity or alkalinity of a solution. The pH scale normally ranges from 0 to 14. Aqueous answers with a pH much less than 7 are acidic, even as people with a pH extra than 7 are simple or alkaline.
A pH stage of 7.0 is described as "neutral" because the awareness of H3O+ equals the attention of OH− in natural water. Very sturdy acids may have a bad pH, even as very sturdy bases may have a pH extra than 14.
Calculating the pOH
pOH = -log[OH⁻]
pOH = -log(0.00500)
pOH = 2.301
Calculating the pH
pH + pOH = 14.00
Subtracting pOH from each side
pH = 14.00 – 2.301
pH = 11.70
