A student carries out the following experiments and records the following observations. 1. A few drops of a solution of KOH (aq) is added to a solution of Cu(NO3)2 (aq). A blue gelatinous solid forms immediately upon addition. 2. A few drops of a solution of KOH (aq) is added to a solution of NaNO3 (aq). No changes are observed. 3. A few drops of a solution of KOH (aq) is added to an unknown solution that could contain Cu2+(aq) and/or Na+(aq) ions (the solution could contain both ions, just one of the ions, or neither ions). A blue gelatinous solid forms immediately upon addition. Select all of the answers that are consistent with the data from those 3 experiments. Group of answer choices The unknown contains Cu2+(aq) and Na+(aq) The unknown contains Cu2+(aq) The unknown contains Na+(aq) The unknown contains neither Cu2+(aq) or Na+(aq)
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.
