Sodium Chloride is white crystalline solid at room temperature
pure sodium chloride is white
Sodium is in solid form at 20 degrees Celsius.
Solid
Sodium is a solid at 20 degrees Celsius. It melts at 97.8 degrees Celsius and boils at 882.9 degrees Celsius.
Salt is made up of Sodium Chloride (NaCl). In this case, it is the Chloride (Cl) that breaks the composition of water, and causes the freezing point of water to be lowered. Without Chloride, the freezing point of water is 32 degrees Fahrenheit (0 Celcius). With 10% of Sodium Chloride (salt), water freezes at 20 Fahrenheit. With 20% of Sodium Chloride, water freezes at 2 Degrees Fahrenheit.
The amount of sodium chloride that would dissolve in 2 L of water at 20 degrees Celsius depends on if the water is moving. It would dissolve faster in moving water than still sitting water.
To make 20 moles of sodium chloride, you would need 20 moles of sodium ions and 20 moles of chloride ions. This could be achieved by combining 40 moles of sodium atoms with 40 moles of chlorine atoms to form 20 moles of sodium chloride.
At 20 0C the solubility of sodium chloride in water is approx. 360 g/L.
The solubility of sodium chloride at 20 0C is 360,9 g/L.
Sodium chloride is very soluble in water - 360,9 g/L at 20 0C.
A strong relation is between the solubility and the temperature for all substances. For sodium chloride, at the room temperature, the solubility in water is approx. 36 g NaCl/100 g water.
Sodium chloride is very soluble in water: 360,9 g/L at 20 0C.
