Experiment Title

Indication of pH and Buffer Solutions Statement of Purpose Train the preparation of the acetate buffer solution (pH = 4.8) and other solutions. Practice the pH measurements. Test the buffer capacity of the prepared buffer solution.

Hypothesis to test:

- property of buffer solution to keep pH, when the strong acid or base are added; - red cabbage juice acts as a natural indicator, which helps to identify the pH of the solution.

Description of the Experiment

Acetate Buffer Preparation: mix 10 ml of 0.2 M acetic acid with 15 ml of 0.2 M sodium acetate, add 75 ml of distilled water was added. Store in an ...

Abstract

This experiment sort to find an accurate and most viable method that would be used in laboratories to the measurement of iron concentration in aqueous samples. The methodologies that were identified for further analysis included; colorimetric assay (molecular spectroscopy), flame atomic absorption spectroscopy, redox titration (volumetric) and cation exchange chromatography (EMA technique). These methods were analyzed of their advantages and later subjected to a validation test. In the process, a wide range of CRMs were used alongside six other samples that contained unknown iron concentration.

The experiment was thus, geared towards providing answers to statements like; the necessity of quantification of ...
