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.
Question
Transcribed Image Text:+ Titration of Weak Acid with Strong Base
A titration involves adding a reactant of known quantity to a solution of an
another reactant while monitoring the equilibrium concentrations. This
allows one to determine the concentration of the second reactant. The
equation for the reaction of a generic weak acid HA with a strong base is
HA (aq) + OH (aq) →A (aq) + H₂O (1)
A certain weak acid, HA, with a K, value of 5.61 x 106, is titrated with NaOH.
Part A
A solution is made by titrating 9.00 mmol (millimoles) of HA and 3.00 mmol of the strong base. What is the resulting pH?
Express the pH numerically to two decimal places.
