Section 15.6- Acid- Base Titrations Flashcards
1
Q
a solution of accurately known concentration
A
standard solution
2
Q
the technique that involves the gradual addition of a standard solution to a measured volume of solution of unknown concentration until the reaction is complete
A
titration
3
Q
the point at which equal numbers of moles of base and acid have reacted
the vicinity in which the pH rises very steeply
A
equivalence point
4
Q
the point of titration in which the indicator has fully changed color is often called the
A
end point
5
Q
equation for titration
A
VbNb= VaNa
volume of base x normality of base= volume of acid x normality of acid
6
Q
acid rain occurs when the pH is
A
less that 7
