(a) Find the equilibrium constant for following acid dissociation reaction at 25°C. Start your answer by writing the equation for Ka written with ΔG°. NH4+ ↔ NH3 + H+ Is your calculated equilibrium constant (Ka) consistent with the value given in the course handout? (b) Find Ka for the reaction at 10 and 40°C. Discuss how temperature affects fractionation between NH4+ and NH3. (c) NH3 is often called free ammonia as opposed to ammonium ion. While ammonia ions are relatively benign, free ammonia is known to be toxic for microbial growth at high concentration especially in high strength wastewater treatment. Briefly discuss about potential temperature effects on the toxicity in biological wastewater treatment.
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.
