A buffer is prepared by addinh 10.0g of ammonium chloride to 250 mL of 1.0M ammonia solution. pKb of ammonia= 474 MW of ammonium chloride= 53.49g/mol What is the number of moles of 10.0g NH4Cl? What is the molar concentration of NH4Cl? What is the pH of the buffer solution?
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.
