Sodium polyacrylate can retain an enormous quantity of water by an absorption process.
If this is supposed to be an alkene test, then no, hexane will not react with bromine water to take away its color as it is an alkane and therefore contains no double bonds. But bromine water will react with sodium hydroxide; bromine water contains either HCl or H2SO4, both of which will of course react with sodium hydroxide. In addition, I believe (from some experiments like this that I've done recently) that sodium hydroxide will actually react with the free bromine in the bromine water, as evidenced by the change in color from the orange-ish color of bromine water to a pale yellow.
Sort of. Sodium oxide reacts with water to form sodium hydroxide, which is soluble.
The balanced chemical equation for the reaction between sodium and water is: 2 Na + 2 H2O -> 2 NaOH + H2 Since 2 moles of water are needed to react with 2 moles of sodium, 1 mole of water is needed to react with 1 mole of sodium. Therefore, 2.5 moles of sodium will require 2.5 moles of water for the reaction.
The reaction of sodium and water is considered to be a chemical change.
Sodium will normally not react with air. However, it will react with Chlorine. However, that shouldn't be in the air. It will also react with water, but again you need too much water for the air to hold really. That said, going into a steam room with a lump of it would be a bad idea.
hygroscopic compounds, polyacrylamide, sodium acrylate, etc.
Sodium is not dissolved in water; sodium react with water.
Yes, they do react, to form Sodium sulfate and Water
Sodium react vigurously with water.
Sodium chloride doesn't react with water; in water NaCl is dissolved and dissociated in ions.Sodium chloride doesn't react with water; sodium chloride is dissolved and dissociated in water.
Yes.
Sodium will react with water to produce sodium hydroxide (NaOH) and water.
Sodium chloride form with water saline solutions.
Water doesn't react with sodium chloride; sodium chloride is dissociated in water:NaCl----------------------------Na+ + Cl-
Sodium hydrogencarbonate and citric acid react.
Sodium ion exist in water as the product of a dissociation; sodium (metal) react violently with water
Yes.
