Making a solution. Dissolving 08/11/2018

We are learning: The process of dissolving Explain dissolving using the particle model Explain strengths and weaknesses of some particle models Use the particle model to explain some factors which affect the particle model.

Using the diagram below, write in your own words the process of dissolving. THINK LITERACY.

How much sugar will dissolve in 100 ml of water Method. Measure 100 ml of water into a beaker. Add 1 gram of sugar and stir. Repeat until no more sugar will dissolve. Results table. Mass of sugar (g) Observations (dissolved or not)

Particle model of dissolving Using the particle model explain why the water becomes saturated. (Unable to dissolve more sugar) Use the words in the word bank to help you. Word bank Solid Movement Liquid Water Solvent Solute Spread out Stir Saturated Solution Sugar crystal Particles
