Question

1. Acid-base titrations are an example of an:


pH scale reaction


equilibrium reaction


thermonuclear reaction


first order reaction rate


2: The base ionization constant can be described as

The equilibrium constant for the dissociation of a base to OH– and the conjugate acid

The equilibrium constant for the synthesis of a base and an acid in the formation of a salt

The equilibrium constant for the dissociation of a acid to hydrogen and the conjugate base

none of the above

3. The acid ionization constant can be described as:

The equilibrium constant for the synthesis of an acid and base in the formation of a salt

The equilibrium constant for the dissociation of a base into the conjugate acid

The equilibrium constant for the dissociation of an acid to H+ and the conjugate base

none of the above

4. What is the equilibrium constant?

The rate of a chemical reaction

The pressure required for a reaction to meet equilibrium

The ratio of products and reactants when a reaction meets equilibrium

The ratio of theoretical products and reactants before a chemical reaction begins


The equilibrium constant for the dissociation of a base to OH– and the conjugate acid

The equilibrium constant for the synthesis of a base and an acid in the formation of a salt

The equilibrium constant for the dissociation of a acid to hydrogen and the conjugate base

none of the above

Explanation / Answer

1. pH scale reactions.

Acid base reactions are aslo called pH scale reactions because they have a impact on the colour of the pH scale. If the reaction is acidic the pH is below seven. Shades of pink determine the acidic strength. Similarly, if the reaction is basic or alkaline it appears in shades of blue.The pH is above 7. At pH 7 the reaction is neutralized.
