How many grams of citric acid and sodium citrate dihydrate must be added to 1L of water to produce a solution with pH 3.9 and a total solute concentration of 1 mM? (MW Salt = 294.09; MW Acid = 192.13)
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.
How many grams of citric acid and sodium citrate dihydrate must be added to 1L of water to produce a solution with pH 3.9 and a total solute concentration of 1 mM? (MW Salt = 294.09; MW Acid = 192.13)
I found the answer below, but my calculation does not match it. Can you please show me in detail how the calculation from the image below was done? How did they get the amount of citric acid and citrate?
Please make sure that you get the same result and the calculation is completely detailed.
