If sodium metal and chlorine gas mix under the right conditions, they will form salt.
The sodium loses an electron, and the chlorine gains that electron
. This reaction is highly favorable because of the electrostatic attraction between the particles. In the process, a great amount of light and heat is released.
How is salt made from sodium and chlorine?
Sodium chloride, also known as table salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. It is commonly used as a condiment and food preservative. Salt can be created by adding two very reactive elements together: sodium (Na(s) metal and chlorine (Cl2(g) gas.
Does chlorine combine with sodium to table salt?
Chlorine (Cl) is a halogen; it is a highly reactive element that readily gains an electron to fill its outermost shell.
Sodium and chlorine
, two highly reactive elements, combine to form the stable compound sodium chloride (ordinary table salt).
How does sodium bond with chlorine?
Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. It is easiest for sodium to lose its electron and form a +1 ion, and for chlorine to gain an electron, forming a -1 ion. … Ionic bonds between each atom forms a relatively strong bond and a three-dimensional, cubic structure.
How is salt formed?
The salt comes
from weathering and volcanic activity
. The ocean formed very early on in Earth history, as soon as water comes into contact with rock then weathering processes start – these leach (dissolve) the soluble elements preferentially out of the rock (sodium, calcium, magnesium, potassium etc).
What type of reaction is sodium and chlorine?
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na
+
) and a chloride anion (Cl
–
), both ions have complete valence shells, and are energetically more stable. The reaction is
extremely exothermic
, producing a bright yellow light and a great deal of heat energy.
What happens if you mix bleach and salt?
When dissolved in water,
bleach provides OH-
. There will be a neutralization reaction if the salt you use is acidic. There could be a reaction if the salt you use is basic. The salt will be dissolved in a bleach solution.
What causes an ionic bond to form between sodium and chlorine?
In ionic compounds, atoms gain or lose electrons to form ions. … When the atoms of each element first come together, both are electrically neutral. When they get close enough,
an electron transfers from
the sodium to the chlorine. This makes a positive sodium ion, Na+, and a negative chloride ion, Cl-.
What kinds of bonds are formed between water and sodium?
When salt is mixed with water, the salt dissolves because the
covalent bonds
of water are stronger than the ionic bonds in the salt molecules.
Why are sodium and chlorine more active elements?
It takes
more energy to remove
an electron from a sodium atom to form an Na
+
ion than we get back when this electron is added to a chlorine atom to form a Cl
–
ion. Once these ions are formed, however, the force of attraction between these ions liberates enough energy to make the following reaction exothermic.
Why the sea is salty story?
In a story from the Philippines
a man has ordered large blocks of salt to be carried across the sea to build a great white mansion
. The Ocean is angry at being disturbed and sends a great wave to knock the bricks into the sea – where they dissolved and so the sea is salty.
How do we use salt in everyday life?
Salt has long been
used for flavoring and for preserving food
. It has also been used in tanning, dyeing and bleaching, and the production of pottery, soap, and chlorine. Today, it is widely used in the chemical industry.
Which ocean is not salt water?
The
ice in the Arctic and Antarctica
is salt free. You may want to point out the 4 major oceans including the Atlantic, Pacific, Indian, and Arctic. Remember that the limits of the oceans are arbitrary, as there is only one global ocean. Students may ask what are the smaller salty water areas called.
How do you balance sodium and chlorine?
Explanation: How to Balance the Equation Na(s)+Cl2
(g)
→ NaCl . Since there are two chlorine atoms on the left side, there needs to be two chlorine atoms on the right side. So I put a coefficient of two in front of the formula NaCl .
How do you balance hydrogen and chlorine?
The balanced chemical equation for the
hydrogen + chlorine -> Hydrogen Chloride
. The equation is balanced as in the reactants side there are two hydrogens present and the same on the products side. For chlorine as well the same thing goes two chlorine atoms on the reactants side and two on the products side.
What happens when sodium reacts with chlorine to form sodium chloride?
Sodium and chloride form
an ionic bond
. Therefore the sodium atom loses one electron from its outer shell and the chlorine atom gains one electron. As this happens, the electron is transferred from the sodium atom to the chloride atom and so both atoms become ionic and have a full outer shell.
