03 Feb Reactions of alkali
If you think that Chemistry is a very bland and boring subject to understand then we will ask you to think again. Chemistry maybe a very important subject to learn but it has failed to attract the students towards it. Students have many myths and thoughts about Chemistry which have developed inside them because of the various uncleared doubts and concepts left with them.
Miracle Learning Centre can assure you that not a single student who attends our class will ever feel bored or overburdened. In our classes, we implement some modern teaching techniques because of which our classes are exciting and thoroughly enjoyable. We teach through videos, presentations, illustrations to make our lessons exciting.
Our teachers always provide the simplest solution for each topic.
Chemistry tuition classes in Miracle Learning Centre is very useful. If you do not understand chemistry, you must definitely attend the chemistry tuition class at Miracle Learning Centre. Let us learn about reactions of alkali in this chemistry tuition lesson.
Your chemistry tuition teacher at Miracle Learning Centre will teach you that alkali react with acid to form salt and water. This reaction is called neutralisation. The other reaction of an alkali is that alkali react with ammonium salt to form salt, ammonia gas and water. For example, ammonium chloride reacts with sodium hydroxide to form sodium chloride, ammonia gas and water. This is one of the methods to produce ammonia gas in the laboratory. To test for ammonia gas, use a moist red litmus paper. If ammonia is present, the litmus paper will turn blue.
The student at Miracle Learning Centre asked, ” Why farmers cannot add ammonium nitrate and calcium oxide to the soil at the same time ? “
The chemistry tuition teacher at Miracle Learning Centre replied,”Ammonium nitrate is added to the soil as a fertilizer for plants. The plants need to absorb the nitrogen content for growth. Calcium oxide is added to neutralise acidic soil. However, if they are added at the same time, ammonia gas will be produced and escapes into the air. If this happens, the plant will not be able to absorb the nitrogen for growth. So how do we solve this problem? The solution is to add ammonium nitrate alone. After a few days, then calcium oxide is added. In this way, ammonia will not be released into the air.”
Miracle Learning Centre hope you have understood what the reactions of alkali are. Do come to Miracle Learning Centre for more chemistry tuition lessons to learn more about alkali and chemistry.
