(b) (a) Tollen's test. The reaction of silver ions with a sugar such as glucose produces metallic silver. (a) The set-up for the reac- tion. (b) The silvered test tube. Summary and Conceptual Questions The following questions may use concepts from this and pre- iqus chapters. 86. There are many ionic compounds that dissolve in water to a very small extent. One example is lead(II) chloride. When it dissolves an equilibrium is established between the solid salt and its component ions. Suppose you stir some solid PbCl2 into water. Explain how you would prove that the compound dissolves but to a small extent? Is the dissolving process product-favored or reactant-favored? PbCl2(s) Pb2 (aq) 2 CI-(aq) d Tnctic 1. otos: Cengage Learning/Charles D. Winters 85. (a) a precipitaliu tion. The available starting materials are Ba(OH)2, H,SO4, and Na,S04. Write complete, balanced equations for the reactions chosen. (See page 113 for an illustration of the preparation of the compound.) Describe how to prepare zinc chloride by (a) an acid- base reaction, (b) a gas-forming reaction, and (c) an oxidation-reduction reaction. The available starting materials are ZnCO 3, HCl, Cl, HNO3, Zn(OH) 2, NaCl, Zn(NO3)2, and Zn. Write complete, balanced equations for the reactions chosen. 90.
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.
Question:
a.There are many ionic compounds that dissolve in water to a very small extent. One example is lead(II) chloride. When it dissolves an equilibrium is established between the solid salt and it's components ions. Suppose you stir some solid PbCl2 into water. Explain how you would prove that the compound dissolved but to a small extent. Is the dissolving process favored or reactant favored.
