Hey Dear ❤

Here is ur answer☺

1. Mixtures are useful when you want to combine elements of multiple materials into one product. I.E. you want to rehydrate AND replenish electrolytes so you mix salt in water (or buy Brondo.)
2. Mixtures allow you to dilute a pure ingredient into a product with less ingredient per unit volume. I.E. mixing ethanol with water gives you alcohol that doesn’t make your throat feel like fire when you drink it.
3. Mixtures can be useful for obtaining desirable physical properties. I.E. you mix nitroglycerin with diatomaceous earth and you wind up with a relatively stable stick of dynamite as opposed to just nitroglycerin which can explode if you change the thermostat too quickly.
4. Mixtures are a useful tool for teaching dimensional analysis since classifying them in terms of their concentration of ingredients, density, and other physical properties is typically required to use them in any meaningful way.
5. Mixtures are good for demonstrating physical relationships between different types of chemicals based on things such as differences in polarity, surface energy, density, and other key physical properties. I.E. stable Mixtures vs unstable (water and salt =stable whereas water and oil = unstable)
