- Lead poisoning has been a hazard for centuries. Some scholars believe that the decline of the Roman Empire can be traced, in part, to high levels of lead in water from containers and pipes, and from wine that was stored in leadglazed containers. If we presume that the typical Roman water supply was saturated with lead carbonate, PbCO3 (Ksp = 7.4 1014), how much lead will a Roman ingest in a year if he or she drinks 1 L/day from the container?The net ionic equation for the aqueous neutralization reac-tion between acetic acid and sodium hydroxide is different fromthat for the reaction between hydrochloric acid and sodium hy-droxide. Explain by writing balanced net ionic equations.In the neutralization reaction between H2SO4 and NaOH solution, what is the complete balanced equation for this reaction?
