What mass of NaOH would be added to a one liter 0.200 M solution of acetic acid (pKa = 4.76) to adjust the final pH to 4.76? Assume the NaOH won't significantly change the volume. NaOH has a molar mass of 40.0 g.
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.
What mass of NaOH would be added to a one liter 0.200 M solution of acetic acid (pKa = 4.76) to adjust the final pH to 4.76? Assume the NaOH won't significantly change the volume. NaOH has a molar mass of 40.0 g.
Given : Volume of solution = 1 L
Concentration of acetic acid = 0.200 M
And pH of solution = 4.76
Assuming the moles of NaOH added is y and it is less than the moles of acetic acid.
Moles of acetic acid = concentration of acetic acid X volume of solution = 0.200 X 1 = 0.200 mol.
