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.

Part 1-pH of Solutions of Salts:
In this part you will measure the pH values for 0.1 M solutions of the following solutes.
Sodium acetate
Ammonium chloride
Sodium fluoride
Methylammonium chloride
Sodium bicarbonate
Copper(II) sulfate
Iron(III) nitrate
For each solution, place the solution into a small beaker. Rinse and blot the pH electrode,
place the pH electrode into the solution, and read the pH by moving the knob on the
console to pH. Then return the knob to Standby before moving the electrode out of the
solution for rinsing. Record the pH for each solution on your data sheet and then
determine the ion that influences the pH and the equilibrium involved. Finally calculate
the equilibrium constant based on the pH value you measured.

The chemical 5-amino-2,3-dihydro-1,4- phthalazinedione, better known as luminol, is used by forensic scientists in analyzing crime scenes for the presence of washed-away blood. Luminol is so sensitive that it can detect blood that has been diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing minute amounts of blood. Luminol has a molecular weight of 177 g/mol. The forensic technician at a crime scene has just prepared a luminol stock solution by adding 17.0 g of luminol into a total volume of 75.0 mL of H₂O. What is the molarity of the stock solution of luminol?
