Place the steps in order from first to last for confirming the presence of lead(II) ions in a sample. First step Last step Answer Bank Decant the liquid above the white precipitate and add hot water to the white precipitate. Decant the liquid and add NH3 to the white precipitate. The formation of a yellow precipitate confirms the presence of lead(II). Add HCl to the sample. Decant the liquid and add K₂ CrO to the liquid. Decant the liquid and add HNO3 to the liquid. The formation of a white and black precipitate confirms the presence of lead(II). The formation of a white solid confirms the presence of lead(II).
