In this blog post, JonakyBlog will explore the interplay between ammonium molybdate and the iodine clock reaction, shedding light on how this catalyst influences the reaction’s kinetics and the resulting color change.

Understanding the Iodine Clock Reaction

The iodine clock reaction is a classic chemical reaction that involves the interaction between potassium iodate, sodium thiosulfate, and an iodide ion source.


The reaction leads to the formation of iodine, which in turn reacts with starch to produce a blue-black color change.

However, the uniqueness of the reaction lies in its delayed nature, wherein the color change occurs after a precise time period.

Role of Ammonium Molybdate Catalyst

Ammonium molybdate serves as a catalyst in the iodine clock reaction, facilitating the formation of iodine molecules.
