Chapter 12, Problem 12.31P

Interpretation Introduction

Interpretation:

The requited amount of $\text{0}\text{.050}\text{M}\text{EDTA}$ completely react with $\text{50}\text{.0 mL of 0}{\text{.01 M Ca}}^{\text{2+}}\text{and}\text{50}\text{.0 mL of 0}{\text{.01 M Al}}^{\text{3+}}$ should be determined.

Concept introduction:

Volumetric principle:

The volume and concentration of unknown solution is determined by it is titrate with known volume and concentration solution.

The volume and concentration of unknown solution is required equivalent volume and concentration of known solution in the volumetric titration.

${\text{V}}_{\text{1}}{\text{M}}_{\text{1}}\text{=}{\text{V}}_{\text{2}}{\text{M}}_{\text{2}}$

Where,

${\text{V}}_{\text{1}}$ is volume of known solution

${\text{N}}_{\text{1}}$ is concentration of known solution

${\text{V}}_{\text{1}}$ is volume of unknown solution

${\text{V}}_{\text{1}}$ is concentration of unknown solution
