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.
can you show step by step how i could solve the initial concentration for Fe+3 and SCN-, thank you
![[FESCN2+]eq
[Fe3+]eq[SCN-]eq
Keq
(Eqn. 2.8)
1. [Fe3+]; : Calculate initial concentration of Fe3+ based on the dilution that results from adding KSCN
solution and water to the original 0.0020 M Ee(NO3)3 solution. See Step 2 of the procedure for the
volume of each substance used in Trials 1-4. Recall that in order to determine the concentration of
ample that is a dilution of a solution with known concentration, we use M;V; = M;V;.
[Fe3*]:
(mL Fe (NO3)3) · (0.0020M)
total mL
2. Calculate the initial concentration of SCN, based on its dilution by Ee(NO3)3 and water:
(mL KSCN) · (0.0020M)
[SCN-]; =

Solution
Trial 1 : [FeSCN]2+eq = 0.216 x 0.0002/1.102 = 3.92 x 10^-5 M
Trial 2 : [FeSCN]2+eq = 0.327 x 0.0002/1.102 = 5.93 x 10^-5 M
Trial 3 : [FeSCN]2+eq = 0.433 x 0.0002/1.102 = 7.86 x 10^-5 M
Trial 4 : [FeSCN]2+eq = 0.512 x 0.0002/1.102 = 9.29 x 10^-5 M
