Group 15 elements

The elements of group 15 are phosphorus, nitrogen, bismuth antimony, and arsenic. The most abundant element which is present in the air is nitrogen and the percentage of nitrogen present in the air is 78%. In the free state, the elemental nitrogen is present as diatomic gas (N2). In the organic matter obtained from plants and animals, phosphorus is the dominant element present. In nucleic acids, phosphate groups are present. Phosphates are also found in teeth and bones. The other elements arsenic, bismuth, and antimony are found as sulfides. Arsenopyrite, bismuth glance, and stibnite are examples of sulfides of arsenic, bismuth, and antimony respectively.

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!
