How Do Solutes and Solvents Interact to Create Solutions?

Solutions are created when some substances dissolve in others, making a mixture that looks the same throughout.

Solute: This is the substance that gets dissolved, like salt or sugar.
Solvent: This is the substance that helps dissolve the solute, usually a liquid like water.

Molecular Interaction: When a solute mixes with a solvent, it breaks down into tiny particles called molecules or ions.
- For example, when you add table salt (NaCl) to water, it splits into sodium ions (Na $^+$ ) and chloride ions (Cl $^-$ ).
Solvation Process: Water molecules surround the solute particles in a process called solvation.
- This process releases energy, which helps the solute to dissolve better.
Concentration: We can measure how much solute is in a solution using something called molarity (M).
- Molarity is calculated by finding out how many moles of solute are in a liter of solution.
- The formula is: $M = \frac{\text{moles of solute}}{\text{liters of solution}}$

Temperature: Generally, solids dissolve better in warmer liquids.
Pressure: This mainly affects how well gases dissolve in liquids. When you increase the pressure, more gas can mix into the liquid.

Knowing how solutes and solvents interact helps us understand how solutions are made and what they can do!
