Question

Sodium chloride and potassium chloride flame test differentiate

Answer 1

$\huge \bold{ANSWER}$

◼SODIUM CHLORIDE

Sodium chloride is an ionic compound formed when sodium loses its one electron to chloride.

▶Valency of sodium is +1.To be stable like nearest noble gas neon it losses its one electron to chloride radical ,which is in need of one electron to be stable.

${Na}^{+1} \longrightarrow {Cl}^{-1}$

$[{Na}^{+1}][{Cl}^{-1}]$

NaCl.

◼POTASSIUM CHLORIDE

Potassium chloride is an ionic compound formed when sodium loses its one electron to chloride.

▶Valency of potassium is +1.To be stable like nearest noble gas argon it losses its one electron to chloride radical ,which is in need of one electron to be stable.

${K}^{+1} \longrightarrow {Cl}^{-1}$

$[{K}^{+1}][{Cl}^{-1}]$

KCl.

◼$\bold{FLAME \: TEST}$

▶Take sodium chloride and potassium choride in different clean and dry watch glass.

▶Add concentrated hydrochloric acid to both the watch glass.

▶Take a neat and clean platinum loop wire or glass rod, dip it into the solution of salt + conc. HCl and note the colour of flames.

▶Repeat the process two three times.

◼$\bold{OBSERVATION}$

▶The sodium salt will imparts golden yellow flame.

▶Potassium salt will impart liliac flame.

Hence, can be identified.
