Chapter 5, Problem 5.75GP

Interpretation Introduction

Interpretation:

Many pharmaceuticals are marketed with the designation $"HCl"$ appended to the name of the drug. It should be determined that what does the $"HCl"$ means. The type of reaction that would be involved in converting a drug to the $HCl$ form has to be identified along with discussing the advantages of this form of drug.

Concept introduction:

Reactions of ionic compounds can be grouped into three and they are,

1. 1. Precipitation reaction: A precipitation reaction takes place when two solutions of well soluble substances together form a poorly soluble salt.
2. 2. Acid- base neutralization reaction: it is a double displacement reaction in which an acid and a base react to form an ionic compound (salt) and water.
3. 3. Oxidation-reduction reaction: Both the oxidation and reduction reaction occurs together in a chemical reaction. It is also known as redox reaction.

The term solubility reveals the amount of a given substance that can be dissolved in a certain amount of solvent.
