Concept explainers

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.

Back to basics: Remember that the body’s acid-base balance depends on delicately balanced chemical reactions that require the pH of blood to remain slightly alkaline within a normal range of 7.35-7.45. For normal cell function and metabolism, the blood’s pH must stay within this narrow range. A pH greater than 7.45 creates alkaline conditions and a pH lower than 7.35 is too acidic for the body. The cause of acid-base imbalances is either respiratory or metabolic in origin. We talked about respiratory imbalances due to CO2 concentration and pH in Chapter 9. One of the triggering condition for a fusion of Coronovirus (COVID-19) with a human cell is an acidified environment on the surface of the cell. In other words, the virus needs a low pH environment and thrives in it. Once the patient starts experiencing some coughing and minor trouble with breathing, the lungs begin to lose the capacity to eliminate CO2 from the blood stream. Once this happens the virus can spiral very quickly out…
Select the correct answers: “Ocean acidification is a process that occurs when atmospheric carbon dioxide dissolves in the ocean and is subsequently converted into (methane; carbonic acid; carbonate ions; sodium carbonite) . This then causes the pH of the ocean to (increase; decrease; fractionate; multiply) and become more acidic.”
