4. Circle all of the following that will be more soluble in acidic solution than in pure water. Justify your choices. a. Hg₂Cl₂ b. SrF₂ c. Mg(OH)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.
![1. Suppose that a catalyst lowers the activation
barrier of a reaction from 125 kJ/mol to 55 kJ/mol.
By what factor would you expect the reaction rate
to increase at 25°C? (Assume the frequency
factors for the catalyzed and uncatalyzed reactions
are identical.)
2. A Fe³+/Fe half-cell and Sn²+/Sn half-cell under
standard state conditions are connected by a wire
and a 0.1 M NaNO3 salt bridge (assume 298
K).
a. Sketch this galvanic cell with beakers,
indicating the direction of electron flow and
ion flow from the salt bridge.
