Question

Calculate pH and pOH

Calculate pH and pOH for each of the following solutions at 25°C
a. 1.0×10-³ MOH⁻
b. 1.0 MH⁺

Answer 1

Part a

`\text{pOH}=-\log(1.0 * 10^(-3)})=\boxed{3}\\\\\text{pH}+\text{pOH}=14 \implies \text{pH}=\boxed{11}`

Part b

`\text{pH}=-\log(1.0)=\boxed{0}\\\\\text{pOH}+\text{pH}=14 \implies \text{pOH}=\boxed{14}`
