What factor affects the the change in temperature when a salt is dissolved in water?
The binding energy of the molecule compared to the binding energy of the ions it splits into when it is dissolved determines the change in heat of the water. The stronger a molecule is bound, the higher its binding energy and the more heat is needed to break it apart, which cools the water.
What can molecules do when dissolved in water?
Students will make a 2-D model of a salt crystal and use water molecule cut-outs to show how water dissolves salt. After seeing an animation of water dissolving.
When salt is dissolved in water. which is the sovent?
Salt
How many number of observable phase of salt dissolved in water?
1 only water
Salt dissolved in water is a solution therefore?
Dissolved salt is dissociated in ions Na+ and Cl-.
What is a molecule that consists if parts that dissolve easily into water?
Salt, sugar and baking soda.
Why does salt water work better in the process of electrolysis?
Salt water works because electricity needs a conduit to get electrons from one place to another. Salt is a molecule that is able to do this when it is dissolved in water.
How does dipolar nature of water molecule make it an effective solvent for ionic compounds like salt?
according to the "Like dissolves like" in solubility, ionic compounds like salt, the polar materials, can be dissolved in similar polar nature water molecule.
What type of substance is saltwater?
95% of Earth's water contains high concentration of salt, or high salinity
When salt is dissolved?
When salt is dissolved a water sodium chloride solution is obtained.

Is CO2 a base acid or salt?
When CO2 is dissolved with water creates H2CO3 which is a acid
Why does salt separated from a salt water look different than the salt that dissolved in the water?
The separated salt is a crystalline solid; the dissolved salt is dissociated in ions.
When salt is dissolved in water then what will water become?
salt when dissolved in water will become an acidic solution
When salt is dissolved in water. which is the sovent?
Salt
What is water when salt is dissolved in it?
The water doesn't change. However, the salt splits into an anion and a cation. Those ions become surrounded by the water, thus making them no longer visible. But the water is still just water.
