Suppose you had standard .1000 M NaOH ,an indicator, such as phenolphthalein, an analytical balance, and a micro-buret available. Explain how you could determine the (apparent) purity of the para-nitrobenzoic acid you synthesized.
Reduce the production of hazardous waste and encourage recycling and reuse of hazardous materials by charging producers a tax or fee for each unit of waste generated.
Consider a piece of gold jewelry that weighs 9.55 g and has a volume of 0.660 cm^3. The jewelry contains only gold and silver, which have densities of 19.3 {rm g}/{rm cm}^{3} and 10.5 {rm g}/{rm cm}^{3}, respectively.
