25 g of the dilute mixture of H2SO4 and HNO3 is completed to 500 mL with water. When BaCl2 is added to 10 mL of this solution, the precipitate obtained is 362 mg. Another 20 mL portion taken from the solution is neutralized with 39.2 mL of 0.2 M NaOH solution in the presence of phenolphthalein. Calculate the percentage of HNO3 in the starting mixture.
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.
