Samuel performed a series of dilution using hydrochloric acid. From the stock bottle of 0.5190 M HCL, 1 mL was pipetted into a 500 mL volumetric flask A and diluted to the calibrated mark using distilled water. Calculate the pH of the solution in volumetric flask C.
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.
a) Samuel performed a series of dilution using hydrochloric acid. From the stock bottle of
0.5190 M HCL, 1 mL was pipetted into a 500 mL volumetric flask A and diluted to the
calibrated mark using distilled water. Calculate the pH of the solution in volumetric flask
C.
b) A buffer solution can be prepared by mixing 0.02 M NH3 with 0.03 M NH4Cl (Ka = 5.70 x10^(-10)). Calculate the pH of this buffer. Determine the new pH if 1 mL of 0.1 M NaOH is
added to 0.1 L of buffer solution.
