Captain Kirk, of the Starship Enterprise, has been told by his superiors that only a chemist can be trusted with the combination to the safe containing the dilithium crystals that power the ship. The combination is the pH of solution A, described below, followed by the pH of solution C. (Example: If the pH of solution A is 3.47 and that of solution C is 8.15, then the combination to the safe is 3-47-8-15.) The chemist must determine the combination using only the information below (all solutions are at 25oC): Solution A is 50.0 mL of a 0.100 M solution of the weak monoprotic acid HX. Solution B is a 0.0500 M solution of the salt NaX. It has a pH of 10.02. Solution C is made by adding 15.0 mL of 0.250 M KOH to solution A. What is the combination to the safe?
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.
. Captain Kirk, of the Starship Enterprise, has been told by his superiors that only a chemist can be trusted with the combination

The combination is the pH of solution A, described below, followed by the pH of solution C. (Example: If the pH of solution
A is 3.47 and that of solution C is 8.15, then the combination to

Solution A is 50.0 mL of a 0.100 M solution of the weak monoprotic acid HX.
Solution B is a 0.0500 M solution of the salt NaX. It has a pH
of 10.02.
Solution C is made by adding 15.0 mL of 0.250 M KOH to
solution A.
