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.
Given molecule:
HCN
Hydrogen is an element having 1 valence electrons, Carbon is having 4 valence electrons, and nitrogen is having 5 valence electrons.
Thus, the total valence electrons will be 1+4+5 = 10 valence electrons.
Thus, the Lewis structure of HCN molecule is represented as follows:
According to the Lewis structure of HCN molecules there are 4 bonding electron pairs and one non-bonding electron pairs.
Therefore, HCN has 4 bonding groups.
Number of lone pairs = 1
As carbon is forming triple bond with nitrogen and single bond with hydrogen thus, the number of electron groups around carbon is 4.
Thus, the molecular geometry and electron geometry at carbon atom will be linear as it has 2 bonding pairs.
