Qualitative Analysis is the determination of non-numerical information about a chemical species, a reaction, etc. Examples would be observing that a reaction is creating gas that is bubbling out of solution or observing that a reaction results in a color change.
A reagent is a substance or compound that can facilitate a reaction, and they are used in most widely used tests.
Acidity of base is defined as the no of ionizable hydrogen ions (OH-) present in one molecule of a base is called acidity.
Metal oxides which react with both acids as well as bases to produce salts and water are known as amphoteric oxides or hydroxide.
