do so, they need to first prepare 500.0 mL of 1.000 M of the Tris buffer solution of pH 7.5000. The available reagents in the lab are the following: Tris base MW = 121.14 g/mol pKa = 8.07 Tris-HCl MW = 157.56 g/mol Calculate the amounts of tris base and tris-HCl needed to prepare the buffer solution.
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.
The liquid part of the Moderna vaccine contains a Tris (tromethamine) buffer. The purpose of the buffer is to make the pH level of the vaccine near to that of the human body and also to maintain the integrity of the mRNA component.
In a laboratory scale, a biochemist was asked to study the structure of the mRNA component of the Moderna vaccine. To do so, they need to first prepare 500.0 mL of 1.000 M of the Tris buffer solution of pH 7.5000. The available reagents in the lab are the following:
Tris base MW = 121.14 g/mol pKa = 8.07
Tris-HCl MW = 157.56 g/mol
Calculate the amounts of tris base and tris-HCl needed to prepare the buffer solution.
