Testing Sugar Content with Benedict's Solution

Mr. Kobe demonstrates a sugar testing experiment using Benedict's solution. He prepares test tubes with various liquids, including water, apple juice, cola, and yogurt, and adds Benedict's solution to each. The test tubes are then placed in a warm water bath to accelerate the reaction. The color changes in the solutions indicate the presence and amount of sugar, ranging from blue (no sugar) to red (high sugar). The experiment helps identify which liquids have higher sugar content.
