Mixture 1 Mixture 2 Reaction (NR, R, or PR) Description (if R)
CaCl₂ AlCl₃ NR No reaction occurs because all of the ions are soluble in water.
CaCl₂ Fe(NO₃)₃ R A yellow precipitate of iron(III) hydroxide forms.
CaCl₂ AgNO₃ PR A white precipitate of silver chloride forms.
CaCl₂ KSCN NR No reaction occurs because all of the ions are soluble in water.
CaCl₂ Na₃PO₄ PR A white precipitate of calcium phosphate forms.
CaCl₂ Pb(NO₃)₂ PR A white precipitate of lead chloride forms.
CaCl₂ CuSO₄ PR A white precipitate of copper(II) chloride forms.
CaCl₂ BaCl₂ NR No reaction occurs because all of the ions are soluble in water.
CaCl₂ KI NR No reaction occurs because all of the ions are soluble in water.
NR< the No reaction occurs because all of the ions in the mixture are soluble in water.
R, a reaction occurs, but it is not a precipitation reaction. In the case of CaCl₂ and Fe(NO₃)₃, a yellow precipitate of iron(III) hydroxide forms.
PR, a precipitation reaction occurs. In the case of CaCl₂ and AgNO₃, a white precipitate of silver chloride forms.
