Can someone try & help me please ?? I have to get this done tonight . I know it’s a lot but it’s just 3 questions.
1. List at least two chemical reactions that resulted in a yellow, orange, or red precipitate. For these reactions list the possible chemical name of the precipitate. What do these reactions (and the others similar to them) have in common?
2. List a least two chemical reactions that resulted in a white precipitate. For these reactions list the possible chemical name of the precipitate. What do these reactions (and the others with white precipitates) have in common?
3. Of all the reactions you performed, how many resulted in a precipitate and how many did not? Make a general statement about the interaction of aqueous ionic compounds, using the term double - displacement reaction.
