Select all statements that are true. For polyprotic acids, Ka1 is always the largest Ka out of all of the ionization steps. A 0.1 M solution of strong acid (HA) will have a lower pH than a 0.1 M solution of a weak diprotic acid (H2A). All polyprotic acids ionize in a stepwise manner. In aqueous solution, diprotic acids always have a higher concentration of H3O+ than monoprotic acids. The total moles of H3O+ formed in an aqueous solution of polyprotic acid is equal to the sum of the moles H3O+ produced in each step. The last step in the stepwise ionization of a polyprotic acid always goes to completion (i.e., 100% ionization). Sulfuric acid is a strong acid. Therefore, it does not ionize in steps. In aqueous solution, triprotic acids always have a higher concentration of H3O+ than diprotic acids.
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.
