<u>Answer:</u>
<u>For a:</u> Lead iodide is a yellow precipitate.
<u>For b:</u> Barium sulfate is a white precipitate.
<u>For c:</u> Ferric hydroxide is a brown precipitate.
<u>For d:</u> Copper (II) hydroxide is a blue precipitate.
<u>Explanation:</u>
Precipitation reaction is defined as the reaction where a solid precipitate (solid substance) is formed at the end of the reaction. It is insoluble in water.
For the given options:
- <u>For (a):</u>
The chemical reaction between KI and lead (II) nitrate follows:
The iodide of lead is generally insoluble in water. Thus, lead iodide is a yellow precipitate.
- <u>For b:</u>
The chemical reaction between barium chloride and sulfuric acid follows:
The sulfate of barium is insoluble in water. Thus, barium sulfate is a white precipitate.
- <u>For c:</u>
The chemical reaction between NaOH and ferric chloride follows:
The hydroxide of iron is insoluble in water. Thus, ferric hydroxide is a brown precipitate.
- <u>For d:</u>
The chemical reaction between NaOH and copper sulfate follows:
The hydroxide of copper is insoluble in water. Thus, copper (II) hydroxide is a blue precipitate.
