Table salt (NaCl) and glucose (C6H12O6) are both solids that dissolve in water. Table salt is made of atoms, and glucose is made of molecules.

What is the difference between these two solids when they dissolve?

Responses

When table salt dissolves, it breaks down into separate atoms, surrounded by water. When glucose dissolves, it breaks down into glucose molecules, surrounded by water.

The correct response about the difference between how table salt (NaCl) and glucose (C6H12O6) dissolve in water is:

When table salt dissolves, it breaks down into separate ions (sodium ions Na+ and chloride ions Cl-), surrounded by water. When glucose dissolves, it remains as intact glucose molecules, which are also surrounded by water.

None of the provided responses accurately represent this correct information, but the first option comes closest in terms of conveying the idea that salt breaks into ions while glucose dissolves as whole molecules.

To clarify:

  • Table salt (NaCl) dissociates into sodium (Na+) and chloride (Cl-) ions when it dissolves in water.
  • Glucose (C6H12O6) dissolves in water as whole glucose molecules.
