Fluoridation of city water supplies has been practiced in the United States for several decades. It is done by continuously adding sodium fluoride to water as it comes from a reservoir. Assume you live in a medium-sized city of 150,000 people and that 660 L (170 gal) of water is used per person per day. What mass of sodium fluoride (in kilograms) must be added to the water supply each year (365 days) to have the required fluoride concentration of 1 ppm (part per million)that is, 1 kilogram of fluoride per 1 million kilograms of water? (Sodium fluoride is 45.0% fluoride, and water has a density of 1.00 g/cm3.)
You need 300. mL of 0.500-M K2Cr2O7. Which method is best to prepare this solution? Explain your choice. (a) Dilute 250. mL of 0.600-M K2Cr2O7 to 300. mL. (b) Add 50.0 mL water to 250. mL of 0.250-M K2Cr2O7. (c) Dilute 125 mL of 1.00-M K2Cr2O7 to 300. mL. (d) Add 30.0 mL of 1.50-M K2Cr2O7 to 270. mL of water.
Assume that a sample of hard water contains 50. mg/L of Mg2+ and 150 mg/L of Ca2+, with HCO3 as the accompanying anion. What mass of CaO should be added to 1.0 L of this aqueous solution to precipitate all the Mg2+ and Ca2+ as CaCO3 and MgCO3? What is the total mass of the two solids formed?

500 mL of pure water is first added to 500 mL of 0.500 M K2Cr2O7, making a “standard” solution. What volume of the “standard” solution, when diluted to 500 mL, will be needed to produce another “standard” solution of 0.100 M K2Cr2O7?

O KMNO4 doesn't need to be filtered prior to use. O Most commercial samples contain inorganic matter that will react slowly with the KMnO, and cause its decomposition. O KMNO is very stable, but the unstable ions in the commercial packaging materials must be removed prior to use. Most commercial samples of KMnO4 contain some manganese dioxide that must be removed prior to use to avoid further decomposition. Submit Request Answer Part B Why is the KMnO, not stored in a rubber-stoppered bottle? Rubber doesnt make a good seal with the plastic bottles in which permanganate is usually stored. Rubber can oxidize the permanganate solution. P Pearson Copyright 2020 Pearson Education Inc. All righrs reserved. Terms ofUse I Prvacy Policy Permission: 40 DELL

For the best fit line, use a smooth curve. "Mass of Solute per 100 mL of H2O," should be written on the y-axis (use increments of 2g for every box). "Temperature (°C)" should be written on the x-axis (use increments of 10 °C for every 2 boxes).
