Boric acid, H3BO3, is commonly used in eyewash solutions in chemistry laboratories to neutralize bases splashed in the eye: H3BO3 (aq) + 3 NaOH (aq) - 3 H20 (1) + Na3BO3 (aq) A 0.418 M sodium hydroxide solution is used to neutralize a 21.10 mL sample of boric acid. During an experiment, 23.48 mL of sodium hydroxide is required for complete neutralization of the boric acid to a phenolphthalein endpoint. Calculate the number of moles of NaOH used in the reaction.

94. Baking soda (sodium hydrogen carbonate. NaHCO3) is often used to neutralize spills of acids on the benchtop in the laboratory. What mass of NaHCO3 would be needed to neutralize a spill consisting of 25.2 mL of 6.01 M hydrochloric acid solution?
A soft drink contains an unknown mass of citric acid, C3H5O(COOH)3. It requires 6.42 mL of 9.580 × 10−2-M NaOH to neutralize the citric acid in 10.0 mL of the soft drink. C3H5O(COOH)3(aq) + 3 NaOH(aq) → Na3C3H5O(COO)3(aq) + 3 H2O(ℓ) Determine which step in these calculations for the mass of citric acid in 1 mL soft drink is incorrect? Why? n (NaOH) = (6.42 mL)(1L/1000 mL)(9.580 × 10−2 mol/L) n (citric acid) = (6.15 × 10−4 mol NaOH) × (3 mol citric acid/1 mol NaOH) m (citric acid in sample) = (1.85 × 10−3 mol citric acid) × (192.12 g/mol citric acid) m (citric acid in 1 mL soft drink) = (0.354 g citric acid)/(10 mL soft drink) Determine the correct result.
D5W is a solution used as an intravenous fluid. It is a 5.0% by mass solution of dextrose (C6H12O6) in water. If the density of D5W is 1.029 g/mL, calculate the molarity of dextrose in the solution.
The substance KSCN is frequently used to test for iron in solution, because a distinctive red color forms when it is added to a solution of the Fe3+ cation. As a laboratory assistant, you are supposed to prepare 1.00 L of a 0.200 M KSCN solution. What mass, in grams, of KSCN do you need?
You want to prepare a 1.0 mol/kg solution of ethyleneglycol, C2H4(OH)2, in water. Calculate the mass of ethylene glycol you would need to mix with 950. g water.
Potassium hydrogen phthalate, KHCgH4O4, is used to standardize solutions of bases. The acidic anion reacts with strong bases according to the following net ionic equation: HCgH4O4(aq) + OH(aq) CgH4O42(aq) + H2O(l) If a 0.902-g sample of potassium hydrogen phthalate is dissolved in water and titrated to the equivalence point with 26.45 mL of NaOH(aq), what is the molar concentration of the NaOH?
Suppose you dilute 25.0 mL of a 0.110 M solution of Na2CO3 to exactly 100.0 mL. You then take exactly 10.0 mL of this diluted solution and add it to a 250-mL volumetric flask. After Ailing the volumetric flask to the mark with distilled water (indicating the volume of the new solution is 250. mL), what is the concentration of the diluted Na2CO3 solution?
