Problems

  1. 5.00 mL of a 0.1042 M solution of KHP requires 5.18 mL of approximately 0.1 M NaOH for neutralization. What is the exact concentration of the NaOH solution?
  2. 4.93 mL of the standardized NaOH solution from 1) are required to titrate a 5.00 mL aliquot of approximately 0.1 M HCl solution. What is the exact concentration of the HCl solution?
  3. What volume of standardized HCl solution from 2) is needed to exactly protonate the -COO- group in 5.00 mL of a solution containing 0.0386 g of the amino acid, glycine (H2N-CH2-COOH).
  4. What volume of standard NaOH from 2) is required to titrate both protons in the solution from 3)?
