Classify each reaction as precipitation, acid-base, or no reaction. If the reaction is a precipitation, record either the Ksp or solubility of the product to determine if a precipitate is likely to be seen. Use a reference to see if the product formed may be colored or have an odor. If no reaction happens, write NR in the classification line. Thank you!
