Consider the titration of a 20.0-mL sample of 0.105 M HC2H3O2 with 0.125 M NaOH. Determine each quantity. a. the initial pHb. the volume of added base required to reach the equivalence pointc. the pH at 5.0 mL of added based. the pH at one-half of the equivalence pointe. the pH at the equivalence pointf. the pH after adding 5.0 mL of base beyond the equivalence point

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

the answer is symmetrical : )
