1.	The following table shows the tests a student performed on four aqueous solutions A, B, C and D. Write down on your answer sheet the observations (i) to (iv) that were made.TestObservationsConclusions(i) To solution A, calcium nitrate solution and sodium hydroxide solution were added.(i)A contains Ca2+ ions(ii) To solution B sodium hydroxide solution was added(ii)B contains Fe3+ ions(iii) To solution C ammonium hydroxide was added slowly till in excess .(iii)C contains Cu2+ ions(iv) To solution D Lead nitrate solution and sodium hydroxide solution were added.(iv)D contains Pb2+ ions
Answer» Observations: (i) White ppt. of Calcium hydroxide is formed. (ii) Reddish brown ppt. of Fe(OH)₃ is formed. (iii) Pale blue ppt. is formed which gives deep blue solution with excess of ammonium hydroxide. (iv) A white ppt. of Lead hydroxide AgCl is formed.

Answer»

Observations:

(i) White ppt. of Calcium hydroxide is formed.

(ii) Reddish brown ppt. of Fe(OH)₃ is formed.

(iii) Pale blue ppt. is formed which gives deep blue solution with excess of ammonium hydroxide.

(iv) A white ppt. of Lead hydroxide AgCl is formed.
