The rules for constructing the wave functions for the hybrid orbitals are given below: 1. Firstly we have to take the linear combination of wave function of the respective atomic…
We will calculate the bond length, bond energy of CN and CN – species with the help of molecular orbital theory. Hence we first need the electronic configuration of the…
We know that combined wave function is given as: Ψ AB = Ψcovalent + λΨionic The percent ionic character is given by: X 100 Therefore, 20 = 100* 20 +…
Hydrogen and hydroxyl ion concentration in aqueous solutions of acids and bases: The ionic product is very important quantity in aqueous solutions because it controls the relative concentrations of H+…
0.561 g of KOH dissolved in 200 mL of solution will have: Moles of KOH = 0.561 / 56 = 1.0 x 10-2 As molar mass of KOH = 56…
1 mL of 13.6 M HCl is diluted with water to give 1 L of solution: Molarity of the diluted solution is given as: M1 V1 = M2 V2 13.6…
H3O+] = 3.8 x 10-3 pH = – log = – log (3.8 x 10-3) = – (log 3.8 – 3 log 10) = – log 3.8 + 3.0 =…
If we use the relation, pH = – log , we get pH equal to 8. But this is not correct because an acidic solution cannot have pH greater than…
Conjugate acid and base are related as: Base + H+ <—————> acid Acid <—————–> H+ + base Let us consider a weak acid, HA HA (aq) + H2O < —————>…
Sorensen in 1909 discovered a new tern for expressing the concentration of hydrogen ions known as pH or pH scale. The pH of a solution is defined as: The negative…
