What is meant by a weak acid? Acid Dissociation Constant: Ka Answer and Explanation:1 The strength of an Arrhenius acid is solely indicated by the magnitude of its dissociation constant. We consider the dissociation equilibrium of a...
What does a weak acid do in water?Question:What does a weak acid do in water?Acids:Acids are substances that have a pH below 7. They are generally sour in taste and will make blue litmus paper turn red. According to the Bronsted-Lowry definition, an acid will donate a proton to a ...
Because the nitrate ion can accept protons from the ammonium ion (to form HNO3), the nitrate ion is a very weak Brnsted-Lowry base. Because the ammonium ion has an extra proton to donate (in this case to the nitrate ion), it is a Brnsted-Lowry acid. The nitrate ion is based on ...
In chemistry, there are seven "strong" acids. What makes them "strong" is the fact that they completely dissociate into their ions (H+and an anion) when they are mixed with water. Every other acid is a weak acid. Because there are only seven common strong acids, it is easy to commit...
Strong and Weak Acids and Bases. The strength of anacidor abasedepends on their ability to break into their ions or dissociate into water. A strong acid or a strong base completely dissociates (e.g., HCl or NaOH), on the other hand, a weak acid or weak base partially dissociates (e...

pH = pK(a) + log.(["Salt"])/(["Acid"]) 5.8 = 4.8 + log.(["Salt"])/(["Acid"]) or log.(["Salt"])/(["Acid"]) = 1.0 (["Salt"])/(["Acid"]) = "antilog 1.0" = 10 :. (["Salt"])/(["Acid"]) = (1)/(10) = 0.1.

The strength of an acid or base is determined by its dissociation in water; strong acids (like hydrochloric acid) completely dissociate, while weak acids (like acetic acid) do not. Strong bases (like sodium hydroxide) dissociate fully, whereas weak bases (like ammonia) only partially dissociate...
