home challenge iron in cereal. What happens when water is added to total cereal
Your first few words don't make any sense to me.
When water is added to cereal, it becomes soggy.
When water is added to Total cereal, the iron in the cereal can undergo a chemical reaction, resulting in the release of hydrogen gas.
To understand why this happens, we need to discuss a bit of chemistry. Iron, in the presence of water, can undergo a process called oxidation. This means that iron atoms can lose electrons, forming Fe2+ ions. This process is commonly facilitated by the presence of dissolved oxygen and a slightly acidic environment.
Total cereal contains iron in the form of elemental iron, which is added as a nutrient during the manufacturing process. When you add water to the cereal, some of the iron particles come into contact with water molecules, initiating the oxidation process.
As the iron oxidizes and forms Fe2+ ions, it releases electrons. These electrons can react with water molecules, causing them to split into hydrogen ions (H+) and hydroxide ions (OH-). The released hydrogen ions can then combine to form hydrogen gas (H2).
So, when water is added to Total cereal, you may observe the formation of bubbles or effervescence as the iron reacts and releases hydrogen gas.
Please note that this reaction may not occur immediately and can be influenced by factors such as the temperature, pH of the water, and the concentration of dissolved oxygen. The specifics of the reaction may vary depending on the particular formulation of Total cereal and the conditions under which it is tested.
