Answer to Question #200744 in General Chemistry for Abadi

Question #200744

Q1) Compare and contrast each of the following terms. a) acid ionization constant, base ionization constant b) end point, equivalence point

Expert's answer

a) The Acid Ionization Constant, K

The acid ionization represents the fraction of the original acid that has been ionized in solution. Therefore, the numerical value of Ka is a reflection of the strength of the acid. Weak acids with relatively higher Ka values are stronger than acids with relatively lower Ka values.

Strong and Weak Bases and Base Ionization Constant, K

A strong base is a base, which ionizes completely in an aqueous solution. The most common strong bases are soluble metal hydroxide compounds such as potassium hydroxide. Some metal hydroxides are not as strong simply because they are not as soluble.

b) End Point :- point where the indicator changes colour and comes after the equivalence point . weak acids have only one endpoint .

Equivalence point :- The point at which the titrant is chemically equivalent to the analyte in sample . weak acids can have multiple endpoint.
