The goal of the first part of the experiment is to determine the value of n in the formula for sodium percarbonate, Na2CO3·n H2O2. This will not be a whole number as sodium percarbonate is a non-stoichiometric compound. Titration of a 25.0 mg sample of sodium percarbonate revealed that it contains 0.224 millimoles of hydrogen peroxide. Using this amount, the molar masses of hydrogen peroxide and sodium carbonate, and the law of conservation of mass, determine the value of n implied by this data.
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.
