Bases and alkali
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 bases and alkali in this chemistry tuition lesson.
Your chemistry tuition teacher at Miracle Learning Centre will teach you that metals react with oxygen to form metallic oxides. For example, copper react with oxygen to form copper(II) oxide and sodium react with oxygen to form sodium oxide. So copper(II) oxide and sodium oxide are metallic oxides. Metallic oxides can form basic or amphoteric oxides. Basic oxides can be soluble or insoluble in water. Basic oxides that are soluble in water are called alkali. Alkali react with acid to form salt and water. This reaction is called neutralisation.
The student at Miracle Learning Centre asked, ” Why do we need to learn about bases and alkali? “
The chemistry tuition teacher at Miracle Learning Centre replied,” There are many uses for bases and alkali. The toothpaste you use every morning to brush your teeth contains alkali. The food that is stuck between our teeth is acted on by bacteria to produce acid. Using toothpaste will help to neutralise the acid. Alkali is also used in soap and detergent in our daily cleaning activities. You can tell from these two examples that alkali is a very useful substance.”
Miracle Learning Centre hope you have understood what the bases and alkali are. Do come to Miracle Learning Centre for more chemistry tuition lessons to learn more about bases, alkali and chemistry.
