According to the Resource Conservation and Recovery Act (RCRA), waste material is classified as toxic and must be handled as hazardous if the lead concentration exceeds 5 mg/L. By adding chloride ion, the lead ion will precipitate as PbCl2, which can be separated from the liquid portion. Once the lead has been removed, the rest of the waste can be sent to a conventional waste treatment facility. How many grams of sodium chloride must be added to 500 L of a waste solution to reduce the concentration of the Pb2+ ion from 10 to 5 mg/L?

PLUTO a drain cleaner is solid sodium hydroxide that contains some aluminium chips. When PLUTO is added to water, the NaOH dissolves rapidly with the evolution of a lot of heat. The Al reduces H2O in the basic solution to produce [Al(OH)4]- ions and H2 gas, which gives the bubbling action. Write the balanced net ionic and formula unit equations for this reaction
