Write a long note on strong and weak acid.
Answers
Answer:
An acid is said to be strong if it dissociates completely in aqueous solution giving a high concentration of h3o+ ions.
An acid is said to be weak if it dissociates partially in aqueous solution giving a low concentration of h3o+ions.
Answer:
Strong acid: A strong acid is any acid that ionizes completely in solutions. This means it gives off the greatest number of hydrogen ions or protons when placed in a solution.
Ions are charged particles. Since a strong acid gives off a great number of ions as it breaks down, or dissociates, this means strong acids are able to conduct electricity.
The strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid and chloric acid.
Weak acid: A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water.
In contrast, a strong acid fully dissociates into its ions in water. The conjugate base of a weak acid is a weak base, while the conjugate acid of a weak base is a weak acid.
Examples of weak acids include acetic acid (CH3COOH), which is found in vinegar, and oxalic acid (H2C2O4), which is found in some vegetables.
