What are the physical appearance of NaCl before heating?

Before heating, sodium chloride (NaCl), also known as table salt, typically appears as small, white cubic crystals or crystalline powder. It is a colourless substance that is transparent when in its pure form. NaCl has a crystalline structure where sodium and chloride ions are arranged in a cubic lattice. The crystals are hard and brittle and have a melting point of 801°C (1474°F).

Here are some physical characteristics of NaCl before heating:

1. Colour: White or colourless

2. State at room temperature: Solid (crystalline)

3. Crystal structure: Cubic

4. Hardness: Hard and brittle

5. Transparency: Transparent when pure

6. Odour: Odourless

7. Taste: Salty

8. Solubility in water: Very soluble

9. Melting point: 801°C (1474°F)
