Difference between strong acid and weak acid atleat 5 points (class10)

Strong Acid:

Strong acids will dissociate completely to produce H+ ions.

pH values will be around 0 to 1.

Most of the inorganic acids are strong acids in nature.

Ex: H2SO4, HNO3, HCl…etc.

Weak Acid:

Weak acids will dissociate partially to produce H+ions.

pH values will be around 5 to 7.

All organic acids are weak acids.

Ex: CH3COOH, HNO2, H2SO3…etc

Hope it helps.

Answer 2

Answer:

Definition

Strong acid

A strong acid is an acid that ionizes completely in an aqueous solution. A strong acid will always loose a proton (A H+) when dissolved in H2O. In other words, a strong acid is always on its toes and quite efficient in giving off protons.

Weak acid

A weak acid is one that ionizes partially in a solution. It gives off only few of its hydrogen atoms in to the solution. Hence it is less capable than a strong acid.

Electrical conductivity

Strong acid

Strong acids will always show strong conductivity. Strong acids usually pass more current as compared to the weak acids for the same voltage and concentration.

Weak acid

Weak acids have a low conductivity. They are poor conductors and show a low value for current passing

Rate of reaction

Strong acid

Rate of reaction is faster in the strong acids

Weak acid

Rate of reaction is slower in weak acids

Examples

Strong acid

Hydrochloric acid (HCl), Nitric acid (HNO3), Perchloric acid (HClO4), Sulfuric acid (H2SO4), Hydroiodic acid (HI), Hydrobromic acid (HBr), Chloric acid (HClO3).

Weak acid

Sulfurous acid (H2SO3), Acetic acid (CH3COOH), Phosphoric acid (H3PO4), Benzoic acid (C6H5COOH), Hydrofluoric acid (HF), Formic acid (HCOOH), Nitrous acid (HNO2).

pH

Strong acid

In a strong acid, the pH is lower than, generally 3. Strong acids possess a very high concentration of H+ ions (an acid having a pH of 3 has 0.001 moles per liter of Hydrogen ions).

Weak acid

A weak acid has a pH ranging between 3-7.
