Yes, we generally consider any acid that is weaker than the hydronium ion, H3O+ (the strongest acid that can exist in water) it does not dissociate fully.
For example: If we put HF, a weak acid, in water, it will exist in equilibrium with the hydronium ion.
HF + H2O <<---> F- + H3O+
With equilibria like this, we have two acids that are trying to protonate each other's respective conjugate base- the stronger acid will win. Because the hydronium ion is a stronger acid than hydrofluoric acid, it will more easily protonate fluoride than HF protonates water. Therefore we have a good amount of undissociated HF (our weak acid).
Yes, a weak acid will partly dissociate in a solution, meaning that some of the acid molecules will break apart into ions while others remain intact. This results in the formation of both hydronium ions and undissociated acid molecules in solution.
Weak acids will dissociate only partially in water.
Example: acetic acid or oxalic acid
Weak acid like acetic acid partially ionizes in water as their structure is complex

Is H2CO3 a weak acid or strong?
H2CO3, also known as carbonic acid, is a weak acid. It does not fully dissociate in water, resulting in a partial ionization.
Is it possible for a strong acid and a weak acid to have the same pH?
No, strong acids dissociate completely in water, resulting in a lower pH compared to weak acids which only partially dissociate. Therefore, a strong acid will always have a lower pH than a weak acid.
Is hydrofluoric acid a strong acid or weak acid?
Hydrofluoric acid is considered a weak acid. It does not fully dissociate in water, and its acidic properties are less pronounced compared to strong acids like hydrochloric acid.
What of the following is a characteristic of a weak acid?
It completely dissociates in water.
What is the major difference between a strong acid and weak acid?
The major difference between a strong acid and a weak acid is their ability to completely dissociate in water. Strong acids fully dissociate into ions in water, while weak acids only partially dissociate. This results in strong acids having a higher concentration of ions in solution compared to weak acids.

How do you classify a weak acid?
An element is not an acid. An acid is weak when it dissociates to a very small extent. If u have a certain solution of that acid, check if the concentration of the acid itself is close to that of the solution. If they r the same, it is very strong and dissociates completely.
Acetic acid- strong acid or weak acid?
Acetic acid is a weak acid. In solution, it partially ionizes to release hydrogen ions (H+) but does not completely dissociate. Its Ka value is lower than 1, indicating its weak acidic properties.
Which is the strongest electrolyte A. a weak base B. a strong acid C. a neutral solution D. a weak acid?
B. a strong acid. Strong acids completely dissociate into ions in solution, making them the strongest electrolytes.
How can you tell that the solution contains a weak acid?
You can tell that a solution contains a weak acid if it has a pH below 7 but does not completely dissociate in water. Weak acids only partially ionize in solution, resulting in fewer free hydrogen ions. This leads to a less acidic solution compared to a strong acid.
Why is oxalic acid is classified as a weak acid?
Oxalic acid is classified as a weak acid because it only partially ionizes in water, leading to low concentrations of hydronium ions. This results in a weak acid behavior, as it does not completely dissociate into ions in solution.
How do Ka values of weak acid and a strong acid compare?
The Ka value of a weak acid is smaller than the Ka value of a strong acid because weak acids only partially dissociate in solution, resulting in lower concentrations of H+ ions. Strong acids like hydrochloric acid (HCl) completely dissociate in solution, leading to higher concentrations of H+ ions and therefore a larger Ka value.
What is different about what happens to a weak acid molecule and what happens to a strong acid molecule?
In a weak acid molecule, only a small fraction of molecules will dissociate into ions in solution, leading to a lower concentration of H+ ions compared to a strong acid. In contrast, a strong acid molecule will completely dissociate into ions in solution, resulting in a higher concentration of H+ ions.
