Sodium hydroxide is used extensively in acid-base titrations because it is a strong, inexpensive base. A sodium hydroxide solution was standardized by titrating 36.78 mL of 0.1143 M standard hydrochloric acid. The initial buret reading of the sodium hydroxide was 1.52 mL, and the final reading was 39.50 mL. What was the molarity of the base solution?

Standardization of NaOH: Acid Base Titration Objective: In this lab, you will accurately determine the concentration of a solution of sodium hydroxide (NaOH) using a 0.500M potassium hydrogen phthalate (KHP) standard solution. Background: Acid–Base Titrations When an acid reacts with a base, a neutralization reaction occurs. The H+ ions from the acid and the HO– ions from the base combine to form water and are therefore neutralized. The other product of reaction is a salt. For example, hydrochloric acid reacts...

During a titration of a weak base with a strong acid, you are slowing converting molecules of the weak base into molecules of its conjugate acid. For the hypothetical weak base, B we see the following: B (aq) + H30+ (aq) - BH+ (aq) + H20 (1) In the problem below you will be adding some strong acid, but not enough to reach the endpoint of the titration. 2.00 mL of hydrochloric acid added to the weak base 2.00M hydrochloric...
