A solution containing cobalt (I) ions is added to a solution that is 0.034 M Br– and 0.069 M Cl–. What is the identity of the precipitate that forms, and at what concentration of cobalt (I) ions does this begin to occur? Solubility Product Constants: CoCl = 2.1 × 10–5 CoBr = 6.2 × 10–12 No precipitate will form at any concentration of cobalt (I).
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.
A solution containing cobalt (I) ions is added to a solution that is 0.034 M Br– and 0.069 M Cl–. What is the identity of the precipitate that forms, and at what concentration of cobalt (I) ions does this begin to occur?
Solubility Product Constants:
CoCl = 2.1 × 10–5
CoBr = 6.2 × 10–12
CoCl, 9.0 × 10–11 M
CoBr, 3.0 × 10–4 M
CoCl, 6.2 × 10–4 M
CoBr, 1.8 × 10–10 M
As Ksp of CoBr is less than that of CoCl .so precipitation CoBr will starts first.
