Silber4 4.AlgoEOCP.052.] Sodium hydroxide is used extensively in acid-base titrations because it is a strong, inexpensive base. A sodium hydroxide solution was standardized by titrating 29.56 mL of 0.1528 M standard hydrochloric acid. The initial buret reading of the sodium hydroxide was 3.05 mL and the final reading was 39.20 mL. What was the molarity of the base solution
