Which of the following is observed when a solution of iron (III) chloride is mixed with a solution of sodium hydroxide?
Answer Details
When a solution of iron (III) chloride is mixed with a solution of sodium hydroxide, a brown precipitate is formed. This reaction is a classic example of a precipitation reaction, which is a type of chemical reaction where an insoluble solid (precipitate) forms upon mixing two solutions together. In this case, the brown precipitate is iron (III) hydroxide, which is insoluble in water. The reaction can be represented by the following equation: FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl.
