Mechanism of the reaction
We know sodium is a very active metal and chlorine is also a very reactive non-metal. Usually, metals like to eliminate electrons and non-metals such as halogens lượt thích to accept electrons.Sodium readily eliminate its last shell electrons become Na+ cation and chlorine accepts thatelectron to form Cl- anion.
Balanced chemical equation of mãng cầu + Cl2 reactionNa + Cl2 → 2NaClTwo moles of chlorine gas reacts with one mole of sodium khổng lồ produce two moles of sodium chloride.
It is easy khổng lồ balance this reaction by inspection method than redox method. Redox method will takemuch time. But it is useful in balancing large redox equations.
How lớn balance the reaction from redox method?
This is a so easy redox reaction lớn balance and if you are beginner khổng lồ balancing equations, this is also angood example khổng lồ start your redox reaction balancing.
Sodium is oxidized from 0 oxidation state & to +1 oxidation state. Chlorine is reduced lớn -1 oxidation statefrom 0 oxidation state. Write oxidation numbers if each atom close to the atoms.
Check the number of atoms of oxidized and reduced in the reaction (left and right side) & balance them ifthey are not balance, as the next step. In left side, there are two chlorine atoms. Lớn balance them, make twosodium chloride in the right side. Then there are two sodium atoms in the right side of the reaction, but only one in the leftside. Therefore, make two sodium atoms in the left.
Next, find oxidation number differences of oxidized atoms (sodium khổng lồ sodium ion) and reduced atoms (chlorineto chloride). Oxidation number difference of sodium is two & for chlorine it is two. So they are sameand cancel out each other.
Physical changes of the reactionThe solid reactant, sodium reacts with green-yellow gaseous chlorine và produce solid sodium chloridewhich is a trắng crystalline solid.
This reaction occurs in a rapid rate because both reactants are very reactive. Sodium is a group 1 metal whichlikes to remove its outer electrons và chlorine desired to lớn take electrons from outside.
Enthalpy of sodium and chlorine reaction
Reaction of sodium và chlorine is an exothermic one (heat is released from the reaction).Enthalpy of the reaction is taken as enthalpy of formation of two moles sodium chloride.Standard enthalpy of reaction = -411.12 kJEntropy of the reaction (2980C) = 72.10 J/(K mol)Let"s vì a simple calculation.You are going to lớn mix 4 mol of sodium & 2 mol of chlorine gas. How much energy is released from the reaction? Standard enthalpy of formation of sodium chloride = -411.120 kJ/mol
Definition of Standard enthalpy of formation of sodium chloride: When 1 mol of sodium chloride is formed, 411.120 kJ is released to lớn the outside. If 2 mol of sodium chloride is formed, 411.120 * 2 kJ is released lớn the outside.
Now you know, released heat depends on the formed sodium chloride amount. Now you now we have khổng lồ find out how much sodium chloride is produced in this question.
According to the stoichiometry, to react with 1 mol of chlorine gas, 2 mol of sodium is required. Because of this, lớn react with 2 mol of chlorine gas, 4 mol of sodium is required và there is 4 mol at the beginning of the reaction.Released heat = 411.120 kJ/mol* 4 molReleased heat = 1644.480 kJ
How khổng lồ know, reaction was occurred?
If you set considerable amount of chlorine gas và sodium, you can see the reaction is being occurred beacause reaction beaker will be red colour due khổng lồ emission of large heat.If amount of reactants is low, performqualitative analysis testings for sodium ion và chloride ion.
QuestionsAsk your chemistry questions and find the answersthe hàng hóa metal sodium reacts with clorine gas in a composition reaction
When sodium reacts with clorine gas, sodium chloride (NaCl) is given as the product. Yes. This is a composition reaction because two compounds combine together & produce one compound as product.
I want lớn prepare sodium chloride by a reaction. I have studied several reactions possible for sodium chloride production. One way is reaction of sodium and chlorine gas. Other way is reaction of hydrochloric acid & aqueous sodium hydroxide reaction. I want lớn know, what is the best method lớn prepare sodium chloride from these two methods?
First thing is, in which phase sodium chloride want? Solid or aqueous or liquid NaCl? You have to lớn plan your method according to lớn the physical state of sodium chloride.
Reaction of sodium và chlorine is the direct way khổng lồ prepare sodium chloride if you need solid NaCl. But, this reaction is too dangerous because it emitts large amount of energy và chlorine is a deathly toxic gas.In the second method, you can prepare sodium chloride in aqueous state. So you need to remove water by a separation method, if you need solid sodium chloride.If you need aqueous sodium chloride, this is the best way to do.What"s about potassium & chlorine? Is it similar lớn sodium and chlorine reaction?
Yes. Potassium reacts with chlorine and produce potassium chloride.2K + Cl2 → 2KClsodium và chlorine word equation?Sodium + Chlorine gas → Sodium chloridelithium metal reaction with chlorine gas equation
Lithium reacts with chlorine gas as sodium does. So equation is very similar khổng lồ sodium & chlorine gas reaction.2Li + Cl2 → 2LiClsolid sodium reacts with chlorine gas khổng lồ produce solid sodium chloride, is this true?
Yes. Reaction happens.what is the reaction equation for sodium metal and chlorine gas
Na + Cl2 → NaCl , this is not the balaced equation. This equation denotes only reactants and products.
