Bleaching powder is an unstable compound that decomposes over time. Which of the following is the reason for this?
Bleaching powder readily absorbs moisture from the air, causing it to decompose.
The hypochlorite ion in bleaching powder is inherently unstable and decomposes over time.
Bleaching powder reacts with organic matter in the air, causing it to decompose.
Bleaching powder is a complex compound that breaks down into simpler compounds over time.
Answers (1)
Bleaching powder readily absorbs moisture from the air, causing it to decompose. Bleaching powder is a hygroscopic compound, meaning it readily absorbs moisture from the air. When bleaching powder absorbs moisture, it can decompose into calcium chloride, calcium hydroxide, and chlorine gas. Hence option A is the correct answer.
Option (B) is incorrect because the hypochlorite ion in bleaching powder is not inherently unstable and decomposes only under certain conditions. Hence option B is incorrect.
Option (C) is incorrect because bleaching powder does not react with organic matter in the air. Hence option C is incorrect.
Option (D) is incorrect because bleaching powder is not a complex compound but rather a mixture of calcium hypochlorite and calcium chloride. Hence option D is incorrect.
