Textbook Problem

If electrodes that are connected to a direct current (DC) source are dipped into a beaker of collodial iron(III) hydroxide, a precipitate collects at the negative electrode. Explain why this happens.

Interpretation Introduction

Interpretation:

The precipitation that occurs at the negative electrode when electrodes are connected to a DC source dipped into a beaker of colloidal iron (III) hydroxide has to be explained.

Explanation

Iron (III) hydroxide is a hydrophobic colloid.  As the colloid forms in water, the excess of iron (III) ions present on the surface, gives excess of positive charge to each crystal. These positively charged crystals repel one another and hence aggregation to larger particles of iron (III) hydroxide is prevented...
