Which of the following statements is/are TRUE? I. There are 2 conjugate acid-base pairs in a Brønsted-Lowry acid-base equation. II. Both H2PO4– and CH3COO– are considered amphiprotic species. III. NH3 can be a Brønsted base but not an Arrhenius base. IV. The stronger the acid mixed with water, the less concentrated its conjugate base. a. II and IV b. II and III c. I and III d. I and IV
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.
