Beautiful, lake colours are formed by dyes with mordants, which paste the dye to the cloth or fabric. Which of the following is a mordar used in dying?
- A. Calcium carbonate
- B. Aluminium sulphate
- C. Calcium hydroxide
- D. zinc phosphate
Step-by-step solution
Mordants are substances used to fix dyes to fabrics by forming a coordination complex with the dye. Aluminium sulphate is a common mordant because it forms insoluble complexes with many dyes, helping them adhere to the fabric. Calcium carbonate, calcium hydroxide, and zinc phosphate are not typically used as mordants in dyeing processes.
