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.
1. AgCl with a Ksp of 1.6E-10 has a higher molar solubility than Ag2CrO4 with a Ksp of 2.0E-12. True or False?
2. The solubility of AgCl(s) in water is higher than its solubility in 0.10M NaCl(aq). The Ksp of AgCl is 1.6E-10. True or False?
3. True or False? In a galvanic cell made by connecting a Zn/Zn2+ half cell to a Au/Au3+ half cell, the cations in the salt bridge flow into the Au half cell.
Zn2+ + 2e- → Zn Eº = -0.76V
Au3++ 3e- → Au Eº = 1.498V
4. Consider a three-bulb system. Given six gaseous atoms, putting two atoms in each bulb has a lower entropy than distributing all six atoms in the middle bulb. True or False?
5. For the reaction O2(g) → O2(l), the reaction is spontaneous at low temperatures. True or False?
