Bleach

B
Detergents

C
Liquid soaps

This CO₃ reacts with Ca and Mg ions to form calcium carbonate (CaCO₃ ) and magnesium carbonate (MgCO₃ ) .

Question 9
1 / -0.25

Some of the detergents are non –biodegradable because

A
They kill the bacteria in water which help in degradation

B
They have a long straight carbon chain difficult to degrade

C
They have highly branched carbon chain difficult to degrade

D
They do not dissolve in water completely

Solution

Non-biodegradable detergents are defined as the type of detergent that has a branched hydrocarbon chain. These are known as non-biodegradable because bacteria cannot act on them . These are one of the sources of pollution. Cetyl methyl ammonium bromide is an example of non-biodegradable.
