Chem 142 Summer 2011 Page 1 of 2 Name ________________________________________ Section ________________ Worksheet 5: Reactions in Solution – Acid/Base and Redox 1. How many mL of a 0.800 M NaOH solution is needed to neutralize 40.00 mL of a 0.600 M HCl solution? 2. What volume of each of the following acids will react completely with 50.00 mL of 0.100 M NaOH? a. 0.100 M HCl b. 0.100 M H 2 SO 3 (two acidic hydrogens) c. 0.200 M H 3 PO 4 (three acidic hydrogens) d. 0.150 M HNO 3 e. 0.200 M HC 2 H 3 O 2 (one acidic hydrogen) f. 0.300 M H 2 SO 4 (two acidic hydrogens) 3. A 25.00 mL solution of sodium hydroxide is titrated to the endpoint (the point where the acid and base have reacted to be completely neutralized) after the addition of 42.95 mL of a 0.1067 M HCl solution. What is the molarity of the sodium hydroxide solution? 4. An acid contains one acidic hydrogen per molecule (i.e., H A). A solution of the acid is made using 2.879 g of the pure acid and distilled water. The acid is titrated to the endpoint with 42.55 mL of a 0.1704 M NaOH solution. What is the molar mass of the acid?
