 For each pair of items determine which has the higher entropy and explain why in a sentence.

Item 1, a 100 mL sample of pure water

Item 2, a sample of water and a sample of vinegar after they have been poured together and stirred


Expert Answer

Step 1

Entropy is used to describe the disorder or randomness in a system. It is the amount of arrangements possible in a system at a particular state. When vinegar and water is mixed together, partial dissociation of the weak acid takes place. Here, the acid molecule does not dissociate completely.

Step 2

When a weak acid dissociates, the aqueous solution becomes more ordered since the ions tend to get surrounded by the water molecules. Hence...
