The Amazing World of Solutes, Solvents, and Solutions

Start here

Stir sugar into tea. It vanishes. Yet every sip is sweet.

Three views of one glass.

This is Chapter 9, The Amazing World of Solutes, Solvents, and Solutions.

What you will learn

  • Three words — solute, solvent and solution.
  • What water dissolves — and what it does not.
  • How much goes in — every solvent has a limit.
  • Warmth — it moves the limit.
  • Saturated — a glass at its limit.
  • Concentration — how strong a solution is.
  • Uniform or not — solutions and other mixtures.
  • Density — the mass in each cm³.
  • Float or sink — compare the density with the liquid.

Need a quick recap?

  • Gaps between them (Particulate Nature of Matter) — gaps sit between particles.
  • Does it dissolve? (Materials Around Us) — some solids dissolve, some do not.
  • Dissolving (Changes Around Us) — dry the water and the grains return.

Stay safe

Nothing here is real material. Every glass is on the screen. Never taste a lab material.
