Final answer:
The source of carbon dioxide for the spinach disk is sodium bicarbonate, which releases carbon dioxide gas when mixed with acid. This process is essential for various reactions, such as in baking, where sodium bicarbonate helps dough rise.
Explanation:
The source of carbon dioxide for the spinach disk is the sodium bicarbonate used in the experiment. When moistened and heated, sodium bicarbonate releases carbon dioxide gas, which is crucial for the process.
The presence of acid in the mix enhances the release of carbon dioxide, with examples of slightly acidic ingredients being honey, molasses, ginger, cocoa, and bran.
Sodium bicarbonate reacts with acids to release carbon dioxide gas and is commonly used in baking to make dough rise.
