Grade 5 science quiz: solutions, solutes, and solvents with answers.

📚 Quick Study Guide

• 💧 Solvent: The substance that dissolves another substance. It's usually a liquid, like water. Think of it as the 'doer' of the dissolving!
• 🍬 Solute: The substance that gets dissolved. It can be a solid, liquid, or gas. Think of it as the 'dissolvee'!
• 🧪 Solution: The mixture formed when a solute dissolves in a solvent. It's a homogeneous mixture, meaning it looks the same throughout.
• 🧮 Formula: Solution = Solvent + Solute
• 💡 Example: In saltwater, water is the solvent, salt is the solute, and saltwater is the solution.
• 🌡️ Factors Affecting Solubility: Temperature and pressure can affect how much solute can dissolve in a solvent.
• 🧐 Concentration: How much solute is present in a given amount of solution.
