Metal sulfides are prepared by bubbling hydrogen sulfide gas, H, S, through an aqueous solution containing the metal ion, and then adjusting the pH. When the solution is saturated with H, S, which occurs when [H, S] = 0.100 M, the equilibrium shown is established. H,S(aq) + 2 H,O1) = s²-(aq) + 2H,O*(aq) Keg = 1.1 x 10-20 An aqueous solution containing 0.0117 M Pb2+ and 0.0117 M Ag+ is saturated with H, S. Above what concentration of S2- will PbS precipitate? The Ksp of PbS is 8.9 x 10-29. [s²-] = M Above what concentration of S2- will Ag, S precipitate? The Kp of Ag, S is 3.3 x 10-50. [s²-] = M If the pH of the solution is adjusted to 2.73, which species will precipitate from the saturated H, S solution? neither species PbS both PbS and Ag,S Ag, S
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.
