Using the Lewis concept of acids and bases, identify the Lewis acid and base in each of the following reactions: Fe(NO3), (s) + 6H,0(1)→Fe(H,O)," (aq) + 3NO, (aq) (CH3),NH(g) + HF(g)(CH3),NH2F(s)
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.
![Lewis concept
A Lewis acid is an electron-pair acceptor, and a Lewis base is an electron-pair donor.
A substance that accepts an electron pair is an acid, such as Fe+ in this example where a pair of electrons on CN- is transferred to the metal:
Fet (aq) + 6CN (aq) → Fe(CN)63 (aq)
A substance that donates an electron-pair is a base, such as water in this example where a pair of electrons on the oxygen of water are transferred to the metal cation core:
Fe(H2O)5]?+ (aq) + H2O(1) = Fe(H2O)6]3+ (aq)
The Lewis concept greatly increases the number of species that can be thought of as acids and bases. It allows cations and species with incomplete octets to be defined as an acid. You can identify a transition
metal cation that act as acids by assessing whether a ligand with transferable electrons donates electrons to the metal core.
Part C
Using the Lewis concept of acids and bases, identify the Lewis acid and base in each of the following reactions:
Fe(NO3)3(s) + 6H,0(1)¬Fe(H2O),* (aq) + 3NO3 (aq)
(CH3),NH(g) + HF(g)→(CH3),NH2F(s)
