Question

Assertion (A): Iron (II) salt solution when reacted with ammonium hydroxide forms a dirty green precipitate.

Reason (R): Iron salts are brown in colour.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

Iron(II) ions react with ammonium hydroxide to form a dirty green precipitate of iron(II) hydroxide, so assertion (A) is true. Iron(II) salts are typically pale green, not brown; hence reason (R) is false.
