(Assume 0.3 g of each molecule, 25 mL for 3 extractions of 3 M HCl): A. 24.27 mLs 8.74.27 mLs C. 24.18 mLs D. 74.18 mLs E. none of the above 10. How much excess base exists in the second step of the procedure? (Assume 0.3 g of each molecule, 25 mL for 3 extractions of 3 M NaOH): A. 2427 mis 8.74.27 mLs C. 24.18 mis D. 74.18 mLs E. 50 mlsExplanation / Answer
Ans 8 a) Amines
All amines should dissolve in acid. These amines are basic in the aqueous solutions. They get completely protonated even by the dilute solutions of the strong acids and form salts of alkyl ammonium ions.
