Welcome, curious minds! I am Alyanna Cabansag in 3D and Today, we're exploring the fascinating world of chemical reactions by mixing some common household liquids.Let's start with set-up number one: water and vinegar.Did you know that vinegar is a weak acid, mainly composed of acetic acid? When we mix it with water, it's like adding a touch of acidity to the neutral pH of water. Watch closely as the two liquids combine.See those bubbles? That's carbon dioxide gas being released as the acetic acid in vinegar reacts with the water.Now, let's move on to set-up number two: water and oil.Oil and water, as you might know, don't mix well. That's because oil molecules are nonpolar, while water molecules are polar. It's like trying to mix oil and vinegar in a salad dressing - they just don't want to stay together!Notice how the oil forms distinct droplets that float on the surface of the water? This is because oil is less dense than water and prefers to stay on top.
