Question

Salt dissolving in water is a physical change.
True or False

Answer 1

Your answer would be true

Step-by-step explanation:

Let's see why our answer would be true.

Just like how honey gets dissolved in lemonade? Well it is a physical change because the substance is still the same, it's just a taste and flavor modification.

Now that we know what honey and lemonade is, lets see why salt in water dissolving is a physical change.

We know that something dissolving in a type of liquid is a physical change because of the substance staying the same right? Well if we add salt to our glass of water, it will make a salty water glass from the ocean but the salt not filtered from our ocean in the earth. However the salt dissolved is a physical change because the substance of the salt we added is still the same ans hasn't changed.

Hope this helps.

Answer 2

The correct answer is True.

Salt dissolving in water is a physical change.

In physical change matter does not undergo any change in its chemical composition. In chemical change matter undergoes change in its chemical composition.

When salt (NaCl) dissolves in water it undergoes a change in the state of matter i.e., it gets converted from the solid state to the aqueous state.

Solid NaCl dissociates in water to form Na⁺ cation and Cl⁻ anion. Both the ions get hydrated i.e., surrounded by water molecules.

NaCl(s) + H₂O--> Na⁺ (aq) + Cl⁻(aq)

NaCl does not undergo any change in its chemical composition, it simply splits into Na⁺ cation and Cl⁻ anion.
