Which of the following is the best choice for a buffer system? 1.equal volumes of 0.1 M ammonia (NH₃ ) and 0.1 M ammonium chloride (NH₄Cl) 2.equal volumes of 2 M weak acid (HA) and 1 M sodium hydroxide (NaOH) 3.equal concentrations of sodium hydroxide (NaOH) and hydrobromic acid (HBr)) 4.equal concentrations of sodium hydroxide (NaOH) and nitric acid (HNO₃) 5.equal volumes of 2 M weak acid (HA) and 0.5 M conjugate base (A⁻ ))
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.
