Suppose you have a solution that might contain any or allof the following cations: Ni2+, Ag+, Sr2+, and Mn2+. Additionof HCl solution causes a precipitate to form. After filteringoff the precipitate, H2SO4 solution is added to the resultingsolution and another precipitate forms. This is filtered off,and a solution of NaOH is added to the resulting solution.No precipitate is observed. Which ions are present in each ofthe precipitates? Which of the four ions listed above must beabsent from the original solution?
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.
Suppose you have a solution that might contain any or all
of the following cations: Ni2+, Ag+, Sr2+, and Mn2+. Addition
of HCl solution causes a precipitate to form. After filtering
off the precipitate, H2SO4 solution is added to the resulting
solution and another precipitate forms. This is filtered off,
and a solution of NaOH is added to the resulting solution.
No precipitate is observed. Which ions are present in each of
the precipitates? Which of the four ions listed above must be
absent from the original solution?
