Question 3 A 1.0-liter solution is made by dissolving n moles of HCI in water. HCl is a strong acid and Kw= 1.00x1014. Calculate the pH of the solution and check whether we can use the assumption that the contribution to the hydronium ion concentration from water can be neglected if: (a) If n 5.0x10-6 (mol) (b) If n = 5.0x107 (mol) (c) The relative error we can accept for the calculation of [H*] is within 5% of the value we would obtain if all sources of hydronium ion were included; that is, assuming we can neglect one (or more) of the sources of hydronium ion. What is the minimum value of n that is acceptable to still use the assumption (i.e., to neglect the contribution of water to the total hydronium ion concentration)?

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.
