Explanation
Bleaching powder releases chlorine or hypochlorous acid, which oxidizes coloured substances but can damage delicate or costly fabrics. It is commonly used for bleaching cotton, linen and paper pulp when the material can tolerate the treatment. Students may choose cotton because they overgeneralize the warning about fabric damage and forget that cotton is a routine application.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
