There is NO relation at all.
Solid. Table salt, which is definitely a solid at room temperature, is sodium chloride.
Sodium chloride is very soluble in water at any temperature.
Yes, sodium chloride is a solid at room temperature.
At room temperature sodium chloride is a solid.
Sodium chloride is a solid at room temperature.
Sodium chloride is easily soluble in water forming sodium chloride aqueous solutions.
At room temperature sodium chloride is neutral.
Density=Mass/Volume
The solubilty of sodium chloride increase with the temperature but the effect is not so important.
Why is it sodium chloride have the highest melting temperature
Given that pure sodium chloride is a solid at room temperature, no it is not soluble.
As temperature increases, the solubility of sodium chloride also increases. This is because higher temperatures provide more energy for the water molecules to break apart the sodium and chloride ions, allowing more sodium chloride to dissolve.
