a. Lead(II) chloride is a white pigment used in 15-century European sculptures. If 275 mL of a 0.134 M Pb(NO3)2 solution is added to 125 mL of a 0.0339 M NaCl solution and the Ksp of lead(II) chloride is 1.7x10-5, will a precipitate form? b. If your answer to part a was YES, calculate the grams of lead(II) chloride in solution. If your answer to part a was NO, calculate the minimum molarity of the 125 mL NaCl solution required to precipitate lead(II) chloride when added to 275 mL of 0.134 M Pb(NO3)2.
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.
