Iron has a high density of 7.87 grams per cubic centimetre and is magnetic. With rare exceptions, wood has low density, lower than the density of water, which means the sawdust most likely will float in water. Also, wood burns. Salt has an intermediate density of 2.17 grams per cubic centimetre and dissolves in water.
No, though the sawdust is capable of absorbing quite a lot of water and will soften as a result, but its cellulose structure will never actually dissolve into the water like salt, sugar, and other substances do.
