Answers
ANSWER:
Part D - Reactions of ionic compounds
This type of reaction is characterized by the formation of a precipitate
Part Reactants Appearance of solution Evidence of a chemical reaction D1 CaCl2 (aq) colorless solution Formation of a white precipitate Na3PO4 (aq) colorless solution D2 FeCl3 (aq) yellow solution Formation of a dark red solution KSCN colorless solution The balanced chemical reactions of each part are
Part Balanced equation Type of reaction D1 Precipitation reaction -
Double replacement reaction
D2 Complexation reaction -
Double replacement reaction
Both reaction are double replacement reactions, the first one produces a precipitate whereas the second one produces a colored complex
Part E - Sodium carbonate and HCl
Reactants Appearance of reactants Evidence of a chemical reaction HCl (aq) colorless solution Formation of bubbles Na2CO3 (s) white powder We were unable to transcribe this imageWe were unable to transcribe this image
