About Simulation

  • You will experience an immersive virtual laboratory environment where you can explore reactions such as burning magnesium, reacting lead nitrate with potassium iodide, and zinc with hydrochloric acid through simulation.
  • With visual aids incorporated into the simulations, you can observe changes in colour, appearance, and the formation of products, aiding in better comprehension of each reaction.
  • You can understand the characteristics and properties of chemical reactions more effectively through interactive simulations.
  • By engaging with the simulations, you can easily identify and differentiate between various types of chemical reactions, enhancing your learning experience.

Chemistry Practical Class

  • Through the simulations, you will learn the specific reactions involved in burning magnesium, reacting lead nitrate with potassium iodide, and zinc with hydrochloric acid, providing a hands-on approach to mastering these chemical processes.

A process that transforms reactants into products is called a chemical reaction. The transformation of reactants into products in a chemical reaction yields certain observable properties that are referred to as characteristics of chemical reactions. These important characteristics are

  • Evolution of a gas
  • Formation of a precipitate
  • Change in colour
  • Change in temperature
  • Change in the state

Any of these general characteristics can tell us whether a reaction has taken place or not.

Burning of magnesium ribbon in the air:

Magnesium is an alkaline earth metal with the symbol Mg. It is a silvery-white metal. Magnesium is a highly inflammable metal. It burns with a dazzling white flame in the air to form magnesium oxide, which is basic in nature.

Chemistry Practical Class

Reaction of lead nitrate with potassium iodide:

The reaction between lead (II) nitrate and potassium iodide results in the formation of yellow lead (II) iodide and potassium nitrate in an aqueous solution. This reaction is an example of a double displacement reaction.

Chemistry Practical Class

When these two solutions are mixed, a yellow precipitate of lead (II) iodide is formed, indicating the occurrence of a double displacement reaction.

Reaction of zinc granules with hydrochloric acid:

Zinc is more reactive than hydrogen, and it displaces hydrogen from dilute acids. Zinc reacts with dilute hydrochloric acid to form zinc chloride and hydrogen gas is evolved. This is a single displacement reaction between a non-metal and a metal.

Chemistry Practical Class

The hydrogen gas produced in this reaction can be observed as bubbles or effervescence. The zinc chloride formed is a salt soluble in water.
