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.
![+ pH of a Strong Acid and a Strong Base
pH is a logarithmic scale used to indicate the hydrogen ion concentration,
[H], of a solution:
pH
-log[H+]
Due to the autoionization of water, in any aqueous solution, the hydrogen
ion concentration and the hydroxide ion concentration. [OH]. are
related to each other by the Kw of water:
K = [H+][OH-]
1.00 x 10-14
where 1.00 x 10-14 is the value at approximately 297 K. Based on this
relation, the pH and pOH are also related to each other as
14.00 = pH + pOH
ри= 2.52

✓ Correct
Because the concentration had two significant figures, the pH has two digits after the decimal point.
Part B
0.75 g of sodium hydroxide (NaOH) pellets are dissolved in water to make 6.5 L of solution. What is the pH of this solution?
