What is the difference between a strong acid and a weak acid?

Interpretation Introduction

Interpretation:

The difference between a strong acid and a weak acid is to be determined.

Concept Introduction:

A acid is a chemical species that accepts electrons, donates protons or releases hydrogen ions (H+) in solutions. Acids display certain characteristics properties that can be used to identify them. They tend to dissolve many metals, have sour taste and readily react with bases to form salts.

Acids react with bases to form salt and water.

Acid turns litmus paper red.

Acids are the ions or molecules that are capable of losing protons or hydrogen ions (H+) and their pH value is always less than 7. The acidic strength of an acid is explained in terms of concentration of hydrogen ions produced in a solution.

A strong acid is one that completely dissociates into its ions in a solution.

A weak acid partially dissociates into its ions in a solution

Common examples of strong acids are hydrochloric acid (HCl), nitric acid (HNO3), sulfuric acid (H2SO4)

Common examples of weak acids are formic acid (HCOOH), acetic acid (CH3COOH).

Explanation of Solution

Strong acids:

A strong acid is an acid that completely dissociates or gets ionized in an aqueous solution. It is a chemical species with a high capacity to lose a proton or hydrogen ion (H+). In water, a strong acid loses a proton, which is readily accepted by a water molecule to form a hydronium ion.

Most of the strong acids are corrosive in nature and must be handled carefully as they cause severe burns to the skin. Common examples of strong acids are hydrochloric acid (HCl), nitric acid (HNO3), sulfuric acid (H2SO4) and so on.

Weak Acids:

A weak acid is an acid that partially dissociates into its ions in an aqueous solution, or water
