They are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). Salts can appear to be clear and transparent (sodium chloride)‚ opaque‚ and even metallic and lustrous (iron disulfide). In many cases the apparent opacity or transparency are

reaction. The p-nitrobenzene azoresorcinol dye was prepared from p-nitroaniline and resorcinol. The diazonium salt formed was from the reaction of the cold solution of dissolved p-nitroaniline in hydrochloric acid and water with the solution of sodium nitrite. Azo coupling was then followed by letting the diazonium react with a solution of resorcinol in water and sodium hydroxide. The resulting mixture was treated with excess hydrochloric acid turning the mixture to a color red. After suction filtration
