Question 1 Report

When H2S is passed into a solution of iron (III) chloride, the solution turns
Answer Details
When H2S is passed into a solution of iron (III) chloride, the solution turns brown. This is due to the formation of a precipitate of iron (III) sulfide (Fe2S3). The reaction is represented as follows: 2FeCl3(aq) + 3H2S(g) → Fe2S3(s) + 6HCl(aq) The brown precipitate of Fe2S3 indicates the presence of iron (III) ions in the solution. Therefore, the correct answer is "Brown".
