Salt We have already learned acid and base undergo reaction to produce salt and water. The positive ion of salt comes from the base and that is why the positive ion is known as basic…

Acid Rain Oxides of non-metals undergo reaction with water and produce various types of acid. Pure air has a mixture of small amount of carbon dioxide and different oxides of oxygen. Animals also breathe out…

Neutralization Reaction We know that acid donates H+ in aqueous solution while base donates OH- ion. Therefore, the mixture of acid and base provides H+ and OH- to produce water. For an example: HCl donates…

Concentrated acid and concentrated alkali are highly corrosive. They can corrode clothes and skin. They can spoil eyes if they go into the eyes. They are added slowly to water and turned into dilute solutions…

Both the compounds potassium hydroxide (KOH) and sodium hydroxide (NaOH)  have ions, but when they are in a solid state, the ions are not free here. The moment when they are dissolved, they become fully ionized…

Properties of Dilute Base The solution prepared by adding a comparatively smaller amount of base in a larger amount of water is called dilute base. 1.  Litmus Test: Take a small amount of sodium hydroxide…

Base   Generally, metals or metal-like reactive radical oxides and hydroxides that undergo reaction with acid and produces salt and water are called bases. Examples: Apart from CaO and KOH, examples of base are sodium…

The acid that contains a comparatively lesser amount of water is called concentrated acid. Different concentrated acids such as a concentrated hydrochloric acid (HCI), concentrated sulfuric acid (H2SO4), concentrated nitric acid (HNO3) etc. are used…
