Answer:
pH: 11
pOH: 3
Explanation:
NaOH is a strong base which means that it dissociates completely in water. It will break apart into Na⁺ and OH⁻ ions.
NaOH ⇒ Na⁺ + OH⁻
Because NaOH dissociates completely into its respective ions in water, the moles of NaOH is equal to the moles of hydroxide ions. So, [OH⁻] = 0.001 M.
Now to find the pOH, use the formula pOH = -log[OH⁻].
pOH = -log[OH⁻]
= -log(0.001)
= 3
The pOH of the solution is 3.
To find the pH, subtract the pOH from 14 since pH + pOH = 14.
14 - 3 = 11
The pH of the solution is 11.
Hope that helps.
