Density of Common Salts

The density of salts can vary depending on the specific type of salt and its crystalline structure. In general, the density of salts is higher than that of water, which means they tend to sink in water.

The following table provides a comprehensive list of density values for different salts at room temperature (approximately 25°C or 77°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
