A student from the Industrial Chemistry course wishes to prepare a 3mol/L solution of phosphoric acid (H3PO4). For this procedure, the student used a 0.2N NaOH solution. Knowing that for 25 mL of the sample (acid), they used 30 mL of the alkaline solution (NaOH), determine the actual concentration of the acid and how much of this same solution is needed to prepare 500 mL of a 0.1N solution. (Data: Molar Mass of H3PO4 = 98g/mol; density = 1.685g/mL; T (%) = 85).
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.
