Acids and Bases

Question 1

What are stronger bases than water?

Answer 1

NH3 and Ch3NH2

Question 2

which compounds are more easily protonated ?

Answer 2

Stronger bases are more easily protonated

Question 3

What does a smaller Ka mean?

Answer 3

smaller Ka means weaker acid

Question 4

What is the electronegativity trend for halogens?

Answer 4

FONCLBRISCH
so F> Cl> >Br > I

Question 5

how does electronegativity and acidity of atoms compare ?

Answer 5

EN and Acidity have OPPOSITE trends
Acidity : increases LEFT and DOWN
EN: increases to RIGHT and Up

Question 6

What is the relationship between weak acid and its conjugate base ?

Answer 6

A weak acid will have a STRONG CONJUGATE BASE

Question 7

What does a pH of & at equivalence point indicate ?

Answer 7

A pH of 7 at the equivalence point is indicative of a strong acid or base

Question 8

according to Le Chatlier’s principle, are acidic or neutral gases more soluble ?

Answer 8

ACIDIC gases tend to be. MORE soluble in water than neutral gases are because they partially dissociate in solution

Question 9

What is best indicator when finding out equivalence point for titrations?

Answer 9

best indicator one that covers the steep part of the titration curve at or shortly after the equivalence point.
