Answer:
14.20
Explanation:
The pH can be calculated as:
KOH is a strong base and it will dissociate completely in the solution as:
[tex]KOH\rightarrow K^++OH^-[/tex]
According to the equation and also mentioned that KOH will dissociate completely. So,
Molarity of the hydroxide ions furnished = Molarity of the KOH = 1.6 M
So,
pOH = -log[OH⁻] = -log(1.6) = -0.20
Also,
pH + pOH = 14
So, pH = 14 - ( - 0.20 ) = 14.20
