Rank the acidity of the red bolded hydrogen on the following molecules from lowest to highest pka. Remember, a low pKa is more acidic than a high pka. Compound 1 OH S-OH Compound 3 O Compound 2 P-OH OH N-H H Compound 4 4
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.
The acidity of a molecule's hydrogen atom (H) depends on the atom's identity or the functional group it is attached to. When H is attached to an atom or functional group that can stabilize the negative charge that results from deprotonation, the H atom is more acidic.
Compound 3 is the most acidic H atom as it is attached to a resonance-stabilized structure which is more acidic because the negative charge is delocalized over multiple atoms.
Compound 4 has a hydrogen atom attached to the resonance-stabilized structure.
H atom attached to the N atom is least acidic due to H atom attached to the least electronegative atom nitrogen (N), the electron density around the H atom is higher, making it less acidic.
