Question
Could you please provide the balanced chemical equation for the reaction
To a dry mortar and pestle add the three starting materials and gently mix the solids. Do not pound dry nitrate salts as they pose a danger of explosion. Rather, use a circular motion to grind the materials. Add a very small drop of water using a glass pipette and then grind the materials slowly using circular motions to pulverize the crystals for 10 min. Note any observations. You should obtain a wet powder. If you obtained a paste, you have added too much water and would have to let the product dry in air before proceeding. Add ethyl acetate (5 mL) to the dry powder and continue to grind to dissolve any unreacted starting material. Assemble a vacuum filtration with a Hirsh funnel wetted with ethyl acetate. When you are ready, turn the vacuum on and transfer the reaction mixture using a glass pipette to the center of the filter paper. Use additional ethyl acetate (3 mL) to transfer the entirety of the product from the mortar, as well as to wash the product. Discard the filtrate in the organic waste bottle and let the precipitate air-dry for 15 min. The product is water soluble and somewhat hygroscopic, avoid its exposure to humidity. Weigh the solids to obtain the percent yield and determine its melting point. Note be that although the product was purified of the organic starting materials by the ethyl acetate wash, there may be unreacted sodium nitrite left. For the purposes of this lab, we will assume that all of the nitrite reacted. However, to fully purify the product, the dye may be washed with saturated sodium chloride solution followed by cold methanol.
