Water dissolves salt because the negative part of a water molecule, the oxygen part, is attracted to the positive part of the salt, the sodium part. … When this happens,
the sugar dissolves in the water
. The sucrose molecule does not come apart into individual carbon, hydrogen, and oxygen atoms.
What happens when you dissolve NaCl in water quizlet?
The sodium chloride crystal dissolves
as its sodium and chlorine ions are pulled into the solution, one by one, by the surrounding water molecules
. The charged ends of the water molecules surround the oppositely charged ends of the sodium chloride ions.
What happens and what is produced when salts dissolve in water?
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together
. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
When salt is dissolved in water the sodium and chloride ions quizlet?
Terms in this set (29) When table salt is dissolved in water, the sodium and chloride ions:
dissociate
.
When salts are dissolved in water they?
Answer: When salts are dissolved in water,
they separate into ions
. Salts are ionic compounds which, when dissolved in the liquid, break up completely into ions.
Is salt dissolving in water chemical or physical?
For example salt dissolving in water is usually considered to be a
physical change
, however the chemical species in salt solution (hydrated sodium and chlorine ions) are different from the species in solid salt.
What type of reaction is salt dissolving in water?
Why Dissolving Salt Is
a Chemical Change
Therefore, dissolving salt in water is a chemical change. The reactant (sodium chloride, or NaCl) is different from the products (sodium cation and chlorine anion). Thus, any ionic compound that is soluble in water would experience a chemical change.
What happens when salt is placed in water quizlet?
Water striders benefit from surface tension. When salt is placed in water
the atoms of the salt start to separate from each other making the molecule rip apart
because salt has a negative and a positive side making it polar and water also is polar and polar molecules attract to other polar molecules.
When something dissolves in water is it a chemical change?
Dissolving salt in water may be considered a
chemical change
or a physical change. If you’re forced to pick a side, most chemists say dissolving a covalent compound (like sugar) is a physical change, but dissolving an ionic compound (like salt) is a chemical change.
How does water dissolve salt quizlet?
Water dissolves in salt because
the negative part of a water molecule, the oxygen part is attracted to the positive sodium ion of the salt
. Also, the positive part of the water molecule, the hydrogen part is attracted to the negative chloride ion of the salt.
Which are factors that affect solvation?
There are two direct factors that affect solubility:
temperature and pressure
. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
What is the name of the substance that does the dissolving?
Things which dissolve are called
solutes
and the liquid in which they dissolve is called a solvent to form a solution.
Which of the following happens when NaCl an ionic compound dissolves in water quizlet?
Which of the following happens when solid sodium chloride dissolves in water?
The attractive forces between the sodium and chloride ions are overcome by the attractive forces between the water and the sodium and chloride ions
.
How long does it take salt to dissolve in water?
Results. Boiling water (70 degrees) – fully dissolved in the
2 minute period
.
What can dissolve?
Things like
salt, sugar and coffee
dissolve in water. They are soluble. They usually dissolve faster and better in warm or hot water. Pepper and sand are insoluble, they will not dissolve even in hot water.
What are the 5 factors that affect solubility?
- Temperature. Basically, solubility increases with temperature.
- Polarity. In most cases solutes dissolve in solvents that have a similar polarity.
- Pressure. Solid and liquid solutes.
- Molecular size.
- Stirring increases the speed of dissolving.
