Differences Between Acid and Base
A base is an aqueous substance that donates electrons, accept protons or release hydroxide (OH-) ions. An acid is a proton donor. While a base is a proton acceptor. Acetic acid (CH₃COOH) and sulphuric acid are two examples of Acid.
Explanation:
Any substance that in water solution tastes sour, changes the colour of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical reactions , is called Acid.
or
Acid are the compound that reacts with base to form salts by chemical reactions. They tastes sour.
ex- nitric acid, sulphuric acid,etc
Difference between acid and base
1.Acid is the substance when dissolved in water, increases the concentration of H+ ions.
Acid is the substance when dissolved in water, increases the concentration of H+ ions. The base is the substance when dissolved in water, increase the concentration of OH- ions.
2.Acids are the proton donor. Bases are the proton acceptor.
3.Sour in taste. Bitter in taste.
4.. Acid Turns blue litmus paper to red. Base Turns red litmus paper to blue.
5.. Ex of acids :- Hydrochloric acid (HCl), Sulphuric acid (H2SO4), Nitric acid (HNO3), Carbonic acid (H2CO3).
ex of Bases Ammonium hydroxide (NH4OH), Calcium hydroxide e(Ca(OH)2), Sodium hydroxide (NaOH).
6.Acids are Used as preservatives, fertilizers.
Bases are Used in gastric medicine (antacid), soaps, detergents, cleanser, antiperspirant armpit deodorant.
