Common household bleach primarily contains which active chemical compound?

Explanation

Common household bleach primarily contains sodium hypochlorite dissolved in water, a compound that acts as a strong oxidizing agent capable of killing many types of bacteria and viruses while also breaking down colored pigments to whiten fabrics and remove stains. Bleach should never be mixed with ammonia-based cleaners, since the combination produces toxic chloramine gas. Because of its strong oxidizing properties, bleach is widely used both for disinfecting surfaces and for laundry whitening. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
