For a weak acid, the key change occurs during the dissociation of the acid in water. The equilibrium constant expression (Ka) can be used to determine the extent of dissociation of the weak acid into its ions. The Ka value is a measure of the strength of the weak acid.
You can differentiate between a strong acid and a weak acid using an indicator by examining the pH change. A strong acid will cause a more significant decrease in pH and produce a more intense color change in the indicator compared to a weak acid, which will cause a less dramatic change in pH and produce a less intense color change.
You should add a weak acid to change the pH of a solution very slightly. Weak acids will have a less dramatic effect on the pH compared to strong acids, allowing for more precise control over the pH adjustment.
Hypochlorous acid is a weak acid. It is a fairly weak acid compared to strong acids like hydrochloric acid.
When a strong acid is added to a buffer solution, the change in pH can be calculated using the Henderson-Hasselbalch equation, which is pH pKa log(A-/HA), where pKa is the acid dissociation constant of the weak acid in the buffer, A- is the concentration of the conjugate base, and HA is the concentration of the weak acid. By plugging in the initial concentrations of the weak acid and its conjugate base, along with the amount of strong acid added, you can determine the change in pH of the buffer solution.

When sodium chloride is added to a solution of a weak acid, the chloride ions from the salt will not react with the weak acid. However, the sodium ions can react with the weak acid to form a salt of the weak acid and a strong acid. This reaction can change the pH of the solution, depending on the relative strengths of the weak acid and the strong acid formed.

The formic acid is a weak acid.

Yes it is a weak acid
Citric acid is considered to be a weak acid.
Hypochlorous acid is a weak acid.
A buffer resists change in pH upon addition of a strong acid because it contains a weak acid and its conjugate base (or a weak base and its conjugate acid) which can neutralize the added acid by donating or accepting protons, thus maintaining the pH. The weak acid and its conjugate base components in the buffer solution help to absorb the added protons or hydroxide ions without significant change in pH.
H2CO3 Carbonic acid is a weak acid because it does not dissociate completely in solution making it a weak electrolyte.
No, NaCl is neither an acid, weak acid, or a (weak) base. It is considered a salt.
