The new chemical formula is [tex] Fe(OH)_{3}[/tex] or ferric hydroxide.
Ion [tex] {Fe}^{3 + } [/tex] will react with NaOH while [tex] {Ni}^{2 + } [/tex] will not. The chemical reaction is as follows -
Chemical reaction stating reaction between [tex] {Fe}^{3 + } [/tex] and NaOH.
[tex] {Fe}^{3 + } [/tex] + NaOH → [tex] Fe(OH)_{3}[/tex] + Na
In the reaction, [tex] {Fe}^{3 + } [/tex] represents ferric ions, NaOH is the chemical formula of sodium hydroxide, [tex] Fe(OH)_{3}[/tex] is the chemical formula of ferric hydroxide and Na represents sodium. The ferric hydroxide precipitates as reddish brown. It does not dissolve in excess is sodium hydroxide.
Chemical reaction stating reaction between [tex] {Ni}^{2 + } [/tex] and NaOH
Nickel does not react with sodium hydroxide due to its basic nature. The reason can be owed to electron donating characteristic of both the metal and base.
