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.

Answer the following questions: 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 1.00 M of the Tris buffer solution of pH 7.45. The available reagents in the lab are the following: pka = 8.07 Tris base Tris-HCI MW = 121.14 g/mol MW = 157.56 g/mol a. Calculate the amounts of tris base and tris-HCI needed to prepare the buffer solution, in moles and grams. After this calculation, it was found that the reagents available were only Tris-base and 1.250M HCI. b. Using these new set of reagents, what amounts (in mL and g) of each are needed for the buffer? Note: You can imagine this similarly to NH3 and NH4Cl After the buffer preparation, 2.000 mL of 1.250 M HCI was accidentally added into the buffer solution c. Calculate the new pH of the solution.
