MCQ
Which of the following is an appropriate use of an anionic detergent?
- ✓Dishwashing liquid
- BPine $- o -$ clean
- CGlass cleaners
- DPowder for front$-$loading washing machines
✓
Answer
Correct option: A.
Dishwashing liquid
Anionic detergents are sodium salts of sulphonated long $-$ chain alcohols or hydrocarbons.
Alkyl hydrogen sulphates formed by treating long $-$ chain alcohols with concentrated sulphuric acid are neutralised with alkali to form anionic detergents.
Similarly, alkyl benzene sulphonates are obtained by neutralising alkyl benzene sulphonic acids with alkali.
In anionic detergents, the anionic part of the molecule is involved in the cleansing action.
Sodium salts of alkyl benzene sulphonates are an important class of anionic detergents.
They are mostly used for household work.
An appropriate use for an anionic detergent is in dish$-$washing liquid.
Anionic detergent is typically used in laundry and automatic dishwasher detergents because they do not ionize in solution and thus, have no electrical charge.
Aqueous liquid dish $-$ washing detergent compositions are prepared that exhibit improved detergent performance and foam stability over a range of water hardness levels.
