Concept explainers

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 equilibri…

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.

Textbook Question

Chapter 4, Problem 28E

The following are equivalent ways of asking about the acidity of an H atom:
• What is the most acidic H on the molecule?
• Which H is associated with the published p K a value?
• Which H on the molecule is easiest to remove?
• Which H on the molecule takes the least energy to remove?
• Which bond to an H is most polarized?
• For which H atom is removal least uphill in energy?
• Which bond to an H atom, when broken, results in the lowest PE conjugate base?
We will often find the last of these questions is easiest to answer. To do this, find all the different Hatoms on the molecule, and draw all possible conjugate bases.Only the lowest-energy one is the “real” conjugate base. Identify this structure, and you have found the most acidic H.
Use this strategy to find the most acidic H on each of the following molecules. Note: Each structure hasat least three different kinds of H’s, so draw at least three unique conjugate bases for each.

Students have asked these similar questions

a. Which of the acids in the table above has the strongest conjugate base? b. What is the structure of the strongest acid in the table above?

Given the following Ka values, which anion is the strongest base? (LOOK AT PICTURE) A. HCO3- B. HC2O4- C. CO32- D. C2O42- E. HPO42-

1.Draw the conjugate acid with formal charge(s) below. If there are electrons around any of the atoms ignore them for now. The details will be addressed in the next section. 2. Now specify the details of the structure that was drawn.N with three single bonds and 2 electrons around the atom in the base becomes a N atom with (blank) bonds. (Negative Charge, No Charge, Positive Charge) ,and (BLANK) electron(s) around the atom in the conjugate acid.
