Is the dissolving of sodium chloride in water endothermic or exothermic reaction?
The dissolving of sodium chloride in water is an exothermic reaction because it releases energy in the form of heat.
Describe a way to remove sodium chloride?
Sodium chloride can be removed from solution by distillation. Boiling a solution of sodium chloride will cause the water to boil off and the sodium chloride to be left behind. If the water vapor is then condensed, the water obtained will be free of sodium chloride.
Is dissolving sodium chloride a physical change?
Yes, dissolving sodium chloride in water is considered a physical change. This is because only the state of matter changes (solid to aqueous solution), and no new substance is formed.
What is the chemical composition of a solution made by dissolving PH NaCl in water?
The chemical composition of a solution made by dissolving NaCl in water is sodium chloride (NaCl) and water (H2O).
What pH is a soultion of sodium chloride in pure water?
it has neither an acidic nor an alkaline pH, it is neutral at pH 7
Why is sodium chloride acidic?
The water solution of sodium chloride is neutral.
Sodium chloride in water?
acidic
What is the process of sodium chloride dissolving in water?
dissociation
Is the dissolving of sodium chloride in water endothermic or exothermic reaction?
The dissolving of sodium chloride in water is an exothermic reaction because it releases energy in the form of heat.
Where is salt water made?
Salt water is obtained by dissolving sodium chloride in water.
Is dissolving sodium chloride a chemical or physical change?
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
What is the equation of sodium cholride dissolving in water?
Sodium chloride disassociates in water to produce Na+ and Cl - ions.NaCl + H2O = Na+ aq and Cl- aq.
What is the chemical equation of this reaction Solid sodium chloride dissolves in water.?
Sodium chloride is dissociated in water: NaCl---------------------Na+ + Cl-
Describe a way to remove sodium chloride?
Sodium chloride can be removed from solution by distillation. Boiling a solution of sodium chloride will cause the water to boil off and the sodium chloride to be left behind. If the water vapor is then condensed, the water obtained will be free of sodium chloride.
What is the molecular formula for NaCl dissolving into water?
Sodium chloride is dissociated in water: NaCl---------------Na+ + Cl-
Can water and sodium chloride bond?
No. Sodium chloride in water dissolves into its individual Na+ ions and Cl- ions due to the polarity of the water molecule. This is not a bonding between water and sodium chloride. In fact there is no chemical reaction at all taking place. The dissolving of the sodium and chloride ions by water is a physical change, and can be reversed by letting the water evaporate.
Is dissolving sodium chloride a physical change?
Yes, dissolving sodium chloride in water is considered a physical change. This is because only the state of matter changes (solid to aqueous solution), and no new substance is formed.
