Question

state any four phycial properties of salt?

Answer 1

PHYSICAL PROPERTIES

Odourless, white, cubic crystalsHygroscopicCharacteristic salty tasteMelting point = 800.8 °CBoiling point = 1465 °CDensity = 2.165 g/cm³Solubility at 25 °C = 35.9 g/100 g waterVapour pressure at 865 °C = 1 mm HgSolid does not conduct electricityLiquid conducts electricityAqueous solution conducts electricity

Answer 2

1) Salts are ionic compounds so they are solid but not very hard. They are brittle.
2) Salts have high melting and boiling points.
3)Salts are soluble in most solvents
4) Salts conduct electricity in their solution form.
