Question
Identify the correct representation of reaction occurring during chloralkali process
Options
`2"NaCl"("l") + 2"H"_2"O"("l") -> 2"NaOH"("l") + "Cl"_2("g") + "H"_2("g")`
`2"NaCl"("aq") + 2"H"_2"O"("aq") -> 2"NaOH"("aq") + "Cl"_2("g") + "H"_2("g")`
`2"NaCl"("aq") + 2"H"_2"O"("l") -> 2"NaOH"("aq") + "Cl"_2("aq") + "H"
_2("aq")``2"NaCl"("aq") + 2"H"_2"O"("l") -> 2"NaOH"("aq") + "Cl"_2("g") + "H"_2("g")`
Solution
`2"NaCl"("aq") + 2"H"_2"O"("l") -> 2"NaOH"("aq") + "Cl"_2("g") + "H"_2("g")`
Explanation -
It is the correct answer since the physical states of all the species involved are correct.
