What is the difference between weak acid and dilute acid

It is important to remember this difference and understand that the scientific context can change the meaning of familiar words. Draw out molecular-level pictures of a dilute solution of a strong acid and a weak acid. Draw out molecular-level pictures of a concentrated solution of a strong acid and a weak acid. What are the similarities and differences between all the representations you have drawn? Consider what you have learned about the energy changes associated with the reaction of a strong acid with water.

But according to the concentration of the acid, there are two types of acid solutions as concentrated acid and dilute acid. Overview and Key Difference 2. What is Weak Acid 3. What is Dilute Acid 4. A weak acid is a compound that partially dissociates into its ions when dissolved in water. Weak aid is the conjugate acid of a weak base. Moreover, a weak acid has a high pH value compared to a strong aid of the same concentration. When writing the chemical equation for the dissociation of a weak acid, we use a double arrow to include both forward and backward reactions because the dissociation of a weak acid is reversible.

A weak acid becomes weak because of the less polar nature of the acid compound; if the compound is more polar, the protons can easily leave the acid molecule, but here, since the compound is less polar, it is difficult to break down the chemical bonds.

Some examples of weak acids include acetic acid, formic acid, HF acid, hydrogen sulfide, etc. Dilute acid is an aqueous solution having a low concentration of acid. Pages: [ 1 ] Go Down.

Acid strength is measured by a K value, and this K value tells us about the extent of ionisation of the acid in a solution.

A weak acid does only partially ionise in water. An example is acetic acid.
