Flashcards do conjunto (6)
- 1What are the main components of a washing powder?Detergent - to do the cleaning
Bleach - to remove coloured stains
Water softener - to soften hard water
Optical brightener - to make whites appear brighter
Enzymes - to break up food and protein stains in low-temperature washes - 2What does washing up liquid contain?Detergent - to do the cleaning
Water - to dissolve and dilute the detergent so that it pours out of the bottler
Water softener - to soften hard water
Rinse agent - to help the water drain off crockery and so it dries quickly
Colour and fragrance - to make the product more attractive to buy - 3Is the head of a detergent molecule hydrophilic or hydrophobic and if so why?It is hydrophilic because the charged head is attracted to water molecules because of its polarity (electrical charge).
- 4Is the tail of a detergent molecule hydrophilic or hydrophobic and if so why?It is hydrophobic because the hydrocarbon tail is non-polar and so it is not attracted to water molecules.
- 5How do detergents work(3 steps each detailed)?1) The hydrophobic end of the detergent molecule forms strong intermolecular forces with the oil droplet, while the hydrophilic end of the molecule forms strong intermolecular forces with the water.
2) As more and more detergent molecules molecules are absorbed into the oil droplet, the oil is eventually lifted off the plate.
3) When it is totally surrounded, the oil droplet can be washed away, leaving the plate clean. - 6What are the molecules that make up a grease stain attracted to each other by?Weak intermolecular forces
