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
We have labeled all the Oxalic Acid bottles "Poison."
What are the toxic effects of
ingesting Oxalic Acid? Write an appropriate chemical equation.
![Stock solutions of each of the reagents are provided at the following concentrations:
0.755 M
[H¿C¿O4]
[MnO,]
0.130 M
We will vary the initial concentration of the Oxalic Acid and Permanganate by varying the
volume of each reagent added to the reaction mixture. The concentration (volume) of only one
species will be varied from one experiment to the next so as to determine the influence of only
the species being varied. Because the endpoint of the reaction is difficult to determine, each
experiment will be performed in triplicate and the results will be averaged. Each experiment will
be prepared as follows:

Label a clean 100mL beaker:
"Oxalic Acid"
Obtain ~75 mL of Oxalic Acid solution and place it in the beaker. Oxalic Acid is
poisonous. Wear gloves when handling solutions containing Oxalic Acid. If some
spills on your skin, rinse it off with copious amounts of water. Large spills require
flushing with water for 15 minutes.
2.
Do the same for a beaker for Water.
3.
Label a clean 50 mL beaker:
"Permanganate Ion"
Obtain ~25mL of Permanganate and place it in the beaker. Permanganate is a strong
oxidizing agent. Handle solutions of Permanganate with gloves.
4.
Obtain a large test tube and clamp it in place over a stir plate. Add a small stir bar to the
test tube.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4d4f45f0-6f0b-4cb6-9f2e-05d769dd18ce%2Fcde26d40-bd91-4736-88ce-e78b71634ae5%2Fazzxj2s_processed.jpeg&w=3840&q=75)
