Question 15 For a solution equimolar in HCN and NaCN, which statement is false? a) This is an example of common ion effect. b) The [H'] is larger than it would be if only the HCN was in solution. c) The [H*] is equal to the Ka. d) Addition of more NaCN will shift the acid equilibrium of HCN to the left. e) Addition of more NaOH will increase [CN] and decrease [HCNJ. Question 16
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.
PLease answer question 16 and 17
