Question

Explain the distinction between strong and weak versus concentrated and diluted
acids. Include diagrams to represent these concepts.

1)

• Strong Acids

Strong acids dissociate fully in water to produce the maximum number of H+ ions.

The greater the number of H+ ions produced, the stronger is the acid.

For example,

HCl, H2SO4

• Weak acids

Weak acids do not fully dissociate and the number of H+ ions produced by by is comparatively less.

For example,

CH3COOH, H2CO3

• Concentrated acids

Concentrated acids have very less water molecules meaning that the concentration of H+ ions is very high.

For example,

HCl( conc.)

• Dilute Acids

In dilute acids the acid molecules are mixed with a large amount of water so that the concentration of H+ ions is less.

For example,

HCl( dil.)

For weak and strong acids, their strength depends upon the number of H+ ions dissociated whereas for concentrated and dilute acids their concentration depends upon the amount of water mixed with the acid.

2) Why the pH values are different in weak and strong acid even tho their conc. is same?

The pH values of strong acids are lower than that of the weak acids.

Since, strong acids dissociate to give more H+ ions their acidic nature is more as compared to weak acids.

Even tho their concentration is same they have different pH values due their different degree of dissociation.

( degree of dissociation mostly signifies the strength of acids according to the number of H+ ions they dissociate into.)
