I chose this experiment because I thought it would be fun. When finished testing it has been agreed that when ice is put on salt it takes a long time to melt. 21 Why does ice melt faster in different liquids? The Salt vs. Sugar formative assessment explores students thinking about the question How does structure influence reactivity? The main idea that is being targeted is for students to think about what is happening at the molecular level during the solution process. Adding salt to the ice/water mix causes a temperature drop that slows the melting rate and increases the freezing rate (3). Repeat steps 4 through 6, using each different liquid instead of the water. Place two gummy bears in the first glass of water. mharchnarion Answer: sugar and iodize salt Explanation: yung sugar white sugar yun ha Advertisement Still have questions? This phenomenon demonstrates freezing-point depression. So when you put a freshwater ice cube in a glass of salt water, the cold water coming off the ice cube doesnt sink at all. 2. Salt, when placed on top of a melting ice cube, will dissolve in the little bit of water that melts first, and the dissolved salt lowers the melting temperature of the ice it's in contact with. 3. So how exactly does salt melt ice in water? Carefully sprinkle teaspoon (tsp. ) Salt, baking soda, and sugar will all act to lower the freezing point of the ice, making it melt quicker than the untouched ice cube. Key Takeaways: How Salt Melts Ice. For Laboratory Work:Please refer to the ACSGuidelines for Chemical Laboratory Safety in Secondary Schools (2016). Outside of the asynchronous vs synchronous challenge of the formative assessment, I found this formative assessmentrather successful in giving students an opportunity to explore aspects they know about molecules and how they interact with each other (specifically, polar intermolecular forces) and see if they can make a model or conclusion about why these chemicals dissolve differently. If you normally keep them in the fridge, be sure to allow them to sit out on the counter overnight until they are all the same temperature. 24 How can you melt ice without salt or heat? This experiment easily proves that salt melts ice faster than sugar. Asian American and Pacific Islander Heritage Month, Five different clear liquids (may be colored), The Great Salt vs. Sugar Dissolving Contest, Using Salt and Sugar to Explore How Substances Dissolve, Tea or iced tea (each at room temperature), 12 clear, plastic cups (10 ounce (300 ml)), One (1 teaspoon) (5. 15 Does ice melt faster on metal or plastic?
