A 0.025 M solution of an unknown organic acid has a pH of 3.23. 2.1 By means of a full calculation, determine the value of the ionisation constant of the conjugate base of this acid.. - You may use “HA” to denote the formula of the acid. - You may make certain assumptions to simplify your calculations 2.2 A certain amount of the sodium salt of the conjugate base of the acid was added to the system. Will the pH of the resulting solution increase or decrease, compared to the original given value?
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
A 0.025 M solution of an unknown organic acid has a pH of 3.23.
2.1 By means of a full calculation, determine the value of the ionisation constant of the conjugate
base of this acid..
- You may use “HA” to denote the formula of the acid.
- You may make certain assumptions to simplify your calculations
2.2 A certain amount of the sodium salt of the conjugate base of the acid was added to the system.
Will the pH of the resulting solution increase or decrease, compared to the original given value? Explain your answer in a short sentence or two.
A weak acid is one that which does not dissociates completely rather the solution contains both dissociated and undissociated forms present in equilibrium.
