Figure out whether whether the pH increases, decreases, or stays the same when the first substance mentioned in each of the multiple choices is added to a solution of the second substance and then pick the correct statement. a) When potassium bromide is added to a solution of potassium hydroxide the pH decreases. b) When NaNO2 is added to a solution of HNO2 the pH decreases. c) When NaNO3 is added to a solution of HCl the pH increases. d) When NaClO4 is added to a solution of NaOH the pH stays the same. e) When Ca(C7H5O2)2 is added to a solution of HC7H5O2 the pH decreases.
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.
