How many grams of NH,Br must be dissolved in 1.00 L of water to produce a solution with pH = 5.16? The Kb of NH3 is equal to 1.8 x 10-5. 1 2 3 Let x represent the original concentration of NH,* in the water. Based on the given values, set up the ICE table in order to determine the unknown. NH, (aq) + H20(1) = H;0*(aq) + NH3(aq) Initial (M) Change (M) Equilibrium (M)
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.
