Answer:
0.001 M OH-
Explanation:
[OH-] = 10^-pOH, so
pOH + pH = 14 and 14 - pH = pOH
14 - 11 = 3
[OH⁻] = 10⁻³ ; [OH-] = 0.001 M OH-
Its a base
as Na+ dissociates in the water and it has no basic nor acidic properties its neutral]
but the F- that also dissociates has certain basic properties
hope that helps
