03 Feb Acid reacts with a metal carbonate
Chemistry tuition classes in Miracle Learning Centre is very beneficial. If you do not understand chemistry, you must definitely try the chemistry tuition class at Miracle Learning Centre. Let us learn about the reaction of acids and a metal carbonate in this chemistry tuition lesson.
Most of us know that air contains 0.03% of carbon dioxide. Carbon dioxide is used during photosynthesis to produce glucose and oxygen. To test for carbon dioxide, we pass the gas into limewater. If the gas is carbon dioxide, a white precipitate will be produced. Your chemistry tuition teacher at Miracle Learning Centre will teach you that in order to produce carbon dioxide in the laboratory, you can add an acid to a metal carbonate to produce salt, carbon dioxide and water. For example, when magnesium carbonate is added to hydrochloric acid, the products are magnesium chloride, carbon dioxide and water.
The student at Miracle Learning Centre asked, ” Why does the limewater produce a white precipitate when we exhale into limewater? Then, when we exhale more air into limewater, the solution turns clear again? ”
The chemistry tuition teacher at Miracle Learning Centre replied,” When carbon dioxide is passed into limewater, an insoluble salt of calcium carbonate is produced. Calcium carbonate is the white precipitate. When more carbon dioxide is passed into the solution, calcium hydrogencarbonate is produced. It turns clear again because calcium hydrogencarbonate is soluble in water.”
Miracle Learning Centre hope you have understood what the reaction between an acid and metal carbonate produces. Do come to Miracle Learning Centre for more chemistry tuition lessons to learn more about acids and chemistry.
Are you struggling with your marks of Physics and Chemistry? Have you been looking for a way to achieve more marks with less struggle? Miracle Learning Centre is very much different from any other chemistry tuition center in Singapore. Our main aim is to generate interest for the subject among the students by making the hardest concepts of A Level Chemistry, O Level Chemistry and JC Chemistry easy digestible for the students. At our classes, our teachers impose the AAA teaching model by which at first they help students to understand their weakness and then make them work on that. But they also keep in mind to make the lessons short and fun filled. The concise notes and suggestions provided by our teachers have proven to be very much useful for the students.
