Bleaching powder is an example of________________?
Correct answer: C. Mixed salt
- A. Normal salt
- B. Double salt
- C. Mixed salt
- D. Complex
Explanation
Bleaching powder is represented approximately as Ca(OCl)Cl or CaOCl2 and contains chloride and hypochlorite ions associated with calcium, so it is classified as a mixed salt. A double salt gives its constituent ions in a definite crystalline combination, whereas bleaching powder is not treated in that way. Students may choose double salt because more than one anion appears in its formula.

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.
