Chapter 2, Problem 1DA

Data analysis If we call each step on the x-axis one volume of base, how many volumes of base must be added to change the pH from 4 to 6?

Summary Introduction

To determine: The volumes of the base need to add on the x-axis to change the pH from 4 to 6.

Introduction: Buffer solution is an aqueous solution that contains a solution of a weak acid and connected base. All living cells and fluid present in the multicellular organism contain a neutral pH.

Explanation of Solution

The basicity of the solution depends upon the ion concentration of H⁺ ions and OH^- ions. Every basic solution has a pH value above 7. The range of basic solution in pH scale lies above 7 till 14. A basic solution is required to neutralize the acid present in the solution that helps to increase the pH. Every step on the x-axis consisting of one volume of base. Therefore, the pH change from 4 to 6 on the x-axis is required two-volume of the base.
