Which of the following solutions exhibits the common ion effect? H₂CO3 and Na₂CO3 NH3 and NH4CI ☐ HNO₂ and KNO2 HC₂H₂O₂ and KNO₂ C₂H5NH₂ and C₂H5NH3Br H₂CO3 and NaHCO3
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.
Q1
Common ion effect is an effect which according to Le Chateliar's principle, states that when an ion is added to a solution of salt which contains the same ion then the ionization of that salt will decrease.
For example,
if we add A+ to the solution if salt AB
AB format('truetype')%3Bfont-weight%3Anormal%3Bfont-style%3Anormal%3B%7D%3C%2Fstyle%3E%3C%2Fdefs%3E%3Ctext%20font-family%3D%22math1aa495e18c7e3a21a4e48923b92%22%20font-size%3D%2216%22%20text-anchor%3D%22middle%22%20x%3D%2210.5%22%20y%3D%2216%22%3E%26%23x21CC%3B%3C%2Ftext%3E%3C%2Fsvg%3E)
A+ + B–
then the overall concentration of A+ will increase which results in backward shift of equilibrium and hence salt AB will be less dissociated.
