One of the following statements is incorrect: o Standardization is not required when the titrant solution molarity is approximate O Back-titration is required when the rate of the reaction slow O A primary standard should be highly pure, has atmospheric stability and absence of hydrated water O Titration error is the difference between equivalence point volume and end point volume O A standard solution should react completely with the analyte with a definite chemical equation

Questions 30-35 refer to the same weak acid/strong base (WA/SB) titration. Prior to the beginning of the titration, there were 0.0090 moles of hypobromous acid present in the flask. The Ką of hypobromous acid is 2.8 x 10-9. (Q30) A 30.00 mL solution of 0.300 M hypobromous acid (HBRO) is being titrated with a solution that is 0.600 M in lithium hydroxide (LIOH). What is the initial solution pH (i.e., when 0.00 mL of titrant have been added)?
