Identifying Acid Dyes Characteristics
The question describes dyes that are salts of sulfonic or carboxylic acids. These dyes possess acidic functional groups (like $-SO3-$ or $-COO-$).
These acidic dyes are attracted to and bind with basic sites (like amino groups, $-NH2$ or $-NHR$) present in fibers such as wool, silk, and polyamides. This ionic interaction forms the basis of their dyeing mechanism.
Analyzing Dye Options
- Acid Dyes: These fit the description perfectly, being salts of acids and dyeing basic fibers.
- Methylene blue and Crystal violet are specific examples of basic dyes, which have the opposite properties – they are cationic and dye acidic fibers.
- Basic Dyes: This category refers to cationic dyes that dye fibers with acidic groups, contradicting the question's description.
Therefore, the dyes described are Acid dyes.
