Question

What is the pOH of a solution of HNO3 that has [OH– ] = 9.50 × 10–9 M?

Answer 1

pOH = 8.02

Step-by-step explanation:

Given:

[OH-] concentration for HNO3 solution = 9.50*10^-9 M

To determine:

pOH of the above solution

Step-by-step explanation:

pOH of a given solution refers to the concentration of OH- ions i.e. the degree of basicity of that solution

`pOH = -log[OH-]\\\\For\ the \ HNO3\ solution:\\\\pOH = -log(9.50*10^(-9)) = 8.02`
