What is dissolution?

Dissolution is when something solid turns into a liquid, like when you mix sugar into water.

Imagine you have a glass of water and a spoonful of salt. When you stir, the salt dissolves, it disappears into the water, making the whole thing taste salty. The salt is still there, but it’s now mixed in with the water so well that you can’t see it anymore.

Think about when you make a lemonade. You add sugar to your glass of water and stir. The sugar dissolves, just like the salt. It goes from being a solid (you can see and feel it) into a liquid, blending in with the water.

Even though you can’t see the sugar anymore, it’s still there, it's just spread out all through the liquid. This is like when you put food coloring in water and stir, the color spreads all around, but you can't see the tiny drops of dye anymore.

So, dissolution is just something solid becoming part of a liquid, like sugar or salt mixing into water, simple, everyday magic!
