A solution contains 0.25 M Ni(NO3)2 and 0.25 M Cu(NO3)2. A. 1.Can the metal ions be separated by slowly adding Na2CO3 aq solution? 2.Will it be complete precipitation or not? 3. which one will precipitate first? Assume that for successful separation 99% of the metal ion must be precipitated before the other metal ion begins to precipitate, and assume no volume change on addition of Na2CO3 solution. Pls show step by step. Ksp of CuCO3 = 1.4 x10-10 Ksp of NiCO3 = 1.42X 10-7 B. If you need to redissolve the salt that was first precipitated, what pH will you use and why ?
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 contains 0.25 M Ni(NO3)2 and 0.25 M Cu(NO3)2.
