Sodium hydroxide is used extensively in acid-base titrations because it is a strong, inexpensive base. A sodium hydroxide solution was standardized by titrating 25.00 mL of 0.1528 M standard hydrochloric acid. The initial buret reading of the sodium hydroxide was 2.24 mL, and the final reading was 39.21 mL. What was the molarity of the base solution?
Complete the following precipitation reactions with balanced molecular, total ionic, and net ionic equations:
You are given solutions of HCl and NaOH and must determine their concentrations. You use 27.5mL of NaOH to titrate 100mL of HCl and 18.4mL of NaOH to titrate 50.0mL of 0.0782M H2SO4. Find the unknown concentrations.
Magnesium is used in lightweight alloys for airplane bodies and other structures. The metal is obtained from seawater in a process that includes precipitation, neutralization, evaporation, and electrolysis. How many kilograms of magnesium can be obtained from 1.00 km3 of seawater if the initial Mg2+ concentration is 0.13% by mass (dof seawater = 1.04 g/mL)?
Ammonia is produced by the millions of tons annually for use as a fertilizer. It is commonly made from N2 and H2 by the Haber process. Because the reaction reaches equilibrium before going completely to product, the stoichiometric amount of ammonia is not obtained. At a particular temperature and pressure, 10.0 g of H2 reacts with 20.0 g of N2 to form ammonia. When equilibrium is reached, 15.0 g of NH3 has formed.
(a) Calculate the percent yield.
(b) How many moles of N2 and H2 are present at equilibrium?
