A patient with respiratory alkalosis has a blood plasma pH of 7.58. What is the [H3O+]pf the blood plasma?

Short Answer

Expert verified

The concentration ofH3O+is3.80×10-7M.

Step by step solution

01

Given information

The pH of the blood sample is7.58.

02

Explanation

pH or "potential of hydrogen" is a scale used to specify the acidity or basicity of a watery solution. Acidic solutions are estimated to have lower pH values than basic or alkaline solutions.

The pH of the blood sample is 7.58.

Therefore,

pH=-log10H3O+⇒H3O+=10-pH⇒H3O+=10-7.58H3O+=3.80×10-7M

Thus, the H3O+concentration is3.80×10-7M.
