Potassium is a very reactive metal, but in compounds it is present as the potassium ion and is not very reactive. For example, dry potassium bicarbonate powder can be used to extinguish burning liquids. Why is there such a difference in the reactivity of potassium metal and the potassium ion? A. The potassium in the bicarbonate salt is a base, but the potassium metal is an acid. B. The potassium in the bicarbonate salt is an acid, but the potassium metal is a base. C. The combustion of the liquids suppresses the potassium's ability to react. D. The potassium metal can readily ionize by losing its one valence electron; the potassium in the bicarbonate salt is already ionized. E. The potassium atom is bonded to an oxygen atom in the bicarbonate salt, but in the metal it is unbound and free to react.
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.
