7) Sodium nitrate is a common preservative utilized in
processed meats. Industrially, it is prepared by the neutralization
reaction of nitric acid and sodium carbonate. In an experiment
utilizing this method, 4 grams of sodium nitrate was obtained which
corresponded to 73 % yield. Given that 75 mL of nitric acid was
reacted with excess sodium carbonate, determine the % w/v of nitric
acid used. Describe how you would prepare the nitric acid solution
used from a 1 M nitric acid solution.
b) Solution R contains the mildly soluble
hydroxide of trivalent metal X as well as the highly soluble
bromide of X. 25 mL of R required 20.65 mL of 0.0109 M
sulfuric acid for complete neutralization. Given that the molar
solubility of the hydroxide in pure water is 0.014 M, determine the
molarity of X in solution R.
