What happens when sugar and salt are added to water? Pour in sugar, shake in salt, and evaporate water to see the effects on concentration and conductivity. Zoom in to see how different sugar and salt compounds dissolve. Zoom in again to explore the role of water.
Explore the conductivity of various materials with this interactive PhET simulation.
Describe and explain the difference in conductivity between strong electrolytes, weak electrolytes, and non-electrolytes. Describe and explain the relationship between the concentration of ions and the conductivity of solutions.
Matchmaker Ionic Bonding Game. In this game, the concept of Valence is clearly demonstrated using interlocking shapes to represent Cations and Anions. The game also allows students to practice their formula-writing skills including both monatomic and polyatomic ions.
Conductivity is a chemical property that can be used to distinguish one solution type from another. For a solution to be conductive, it must consist of electrolytes, mobile particles that have charge, in other words, they must be ions. Conductivity increases with the concentration of ions.
In this game, students investigate the ability of catalysts (H + and an enzyme) to increase the probability of productive bond-breaking collisions. Visible energy meters demonstrate the concept of an energy threshold (Activation Energy) required for reaction.
15 paź 2022 · To observe electrical conductivity of substances in various aqueous solutions; To determine of the solution is a strong or weak electrolyte; To interpret a chemical reaction by observing aqueous solution conductivity. Electrical conductivity is based on the flow of electrons.
