A weak acid is one where the acid only liberates a little number of hydrogen ions (H+) in water. Therefore, they are weak electrolytes.
Compare this to a strong acid, which liberates a lot more hydrogen ions when dissolved in water.
Sulfurous acid H2SO3 is a weak di-protic acid.
H2CO3 is an acid, specifically a weak acid known as carbonic acid. It is formed from the dissolution of carbon dioxide in water.
It is an acid but a very weak acid called Carbonic acid
When weak acids react with strong acids, the strong acid will donate a proton to the weak acid, resulting in the weak acid being protonated. This protonation increases the concentration of the weak acid cation. The conjugate base of the weak acid is formed as a result.
Each salt has it's own pH as different in it's constituents as if it formed from strog acid and strong base it will be neutral as between weak acid and weak base , And if formed from strong acid an weak base it will be acidic salt an so on ..........
No, potassium acetate is a salt formed by the reaction of a strong base (potassium hydroxide) with a weak acid (acetic acid). Potassium acetate is neutral and does not act as an acid in aqueous solutions.
Weak bases
It is the product of a strong acid and a weak base, but is itself a mildly acidic salt.
The anion of a weak acid is typically called a conjugate base. It is formed when the weak acid donates a proton (H+) and becomes negatively charged. The conjugate base is usually less acidic than its parent weak acid.
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.
Salts formed from strong acid and strong base are neither acidic nor basic. Salts formed from strong acid and weak base are slightly acidic. Salts formed from weak acid and strong base are slightly basic.
HIO2 is iodic acid. It is a weak acid that is formed by the reaction of iodine pentoxide with water.
