How is the strength of an acid related to the strength of its conjugate base?
Solution 18Q :
Here, we have to state how is the strength of an acid related to the strength of its conjugate base.
First, let’s see what is an acid and base and then we will discuss on strength of them.
- Acids are chemical agents or substances that release hydrogen ions (H+) into solutions or when added to water. i.e, it is a ion or molecule that donates hydrogen ions or disassociates into hydrogen ions.
- Bases are opposite of acids. A base is a substance that can accept a hydrogen ion (H+) from the solution or another substance and dissociates the hydroxide(OH-) ions into solution. Bases can be used to neutralize acids.
- The amount of ions that get released per molecule will determine the strength of acid and base. The strength of acids and bases are measured using a pH scale. It is a scale that is used to represent the level of acidity in a solution. A solution with a pH of 7 is neutral, and a solution with a pH below 7 is an acid, and a solution with a pH above 7 is a base.
- Strong acids are those that completely dissociates and release all of their hydrogen ions and weak acids are those that partially release their hydrogen ions.
- Strong bases are the ones that completely dissociates hydroxide ions(OH-) into solution and completely accept hydrogen(H+) ions that are in the solution or from other molecules. Whereas, weak bases are ones that partially accept hydrogen ions and dissociates hydroxide(OH-) ions.
