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.
Which of the conjugate bases of the following acids will be strong enough to deprotonate acetylene. Indicate the letter of all that apply:
a. C4H10
b. NH3
c. CH3CH2OH
d. CH3CO2H
e. H
f. HCl
The PKa value of actylene is 25 .
Therefore to deprotonate acetylene , the acid should have value greater than PKa = 25
a) C4H10 CH3CH2CH2CH2- .It has a PKa of 48
b) NH3 NH2- . It has a PKa of 38
c) CH3CH2OH CH3CH2O- . It has a PKa of approx. 4 -5.
d) CH3CO2H CH3CO2- . It has a PKa of approx 16-19.
e) H No conjugate
f) HCl Cl- . It has a PKa of -7
