Which of the following is observed when a solution of iron (III) chloride is mixed with a solution of sodium hydroxide?
A
A gas is evolved
B
A deep blue precipitate is formed
C
The resultant solution turns green turns
D
A brown precipitate is formed
correct option: d
iron(III) chloride is a yellow solution
sodium hydroxide is colourless
iron(III) hydroxide is a reddish brown precipitate
sodium chloride is colourless
So in the reaction, yellow solution when added to sodium hydroxide forms reddish brown precipitate that is insoluble in excess sodium hydroxide.
sodium hydroxide is colourless
iron(III) hydroxide is a reddish brown precipitate
sodium chloride is colourless
So in the reaction, yellow solution when added to sodium hydroxide forms reddish brown precipitate that is insoluble in excess sodium hydroxide.
