Oxalic acid is a diprotic acid that occurs naturally in some plants. Calculate the pH and the concentrations of all species present in a 0.79-M solution. The acid dissociation constants are K = 5.9 x 10-2 and K2 = 6.4 x 10-5. Please see https://youtu.be/trMw9Ry3nxs for assistance. [C204H2] 4.0 60 M [C204H - ] X M 4.0 6.4e-5 M [H+) 4.0 X M pH 4.00 (If only the pH is marked incorrect, the [H+] concentration is slightly off but still accepted by WebAssign. Please review your work for the first question. Consider the percent ionization when reviewing your work.)
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.
I have a test tomorrow and I'm not understanding pls help!
