E2 Acid-Base chemistry & dyspepsia 1

Question 1

What are nucleophiles?

Answer 1

nucleus seeking, is an electron rich species

Question 2

What are electrophiles?

Answer 2

electron seeking, is electron deficient

Question 3

Why is HCl a strong acid?

Answer 3

100% of it dissolves in water to ionise to hydronium and chloride ions (all protons of HCl transferred)

Question 4

Why is acetic acid a weak acid?

Answer 4

only a proportion of its protons are transferred in water

Question 5

What is the definition of a strong acid?

Answer 5

fully ionise in aqueous solutions
transfer all protons to water in aqueous solutions
reaction go completion

Question 6

What is the definition weak acid?

Answer 6

partially ionise in aqueous solutions
do not transfer all protons to water in aqueous solution
reactions in equilibria

Question 7

What is a strong base definition?

Answer 7

fully ionises in aqueous solution

Question 8

What is a weak base definition?

Answer 8

partially ionises in aqueous solutions

Question 9

When is proton transfer represented in bases?

Answer 9

bases that are not ionic salts

Question 10

What is group 1 solubility and base strength?

Answer 10

soluble in water

strongly basic

Question 11

How does group 2 solubility and strength differ down the group?

Answer 11

solubility in water increases down group

base strength increases down group

Question 12

What does amphoteric mean?

Answer 12

compound that is able to act as an acid or a base

Question 13

What is the definition of a conjugate acid?

Answer 13

the acid (proton donor) on the product side of the reaction

Question 14

What is the definition of a conjugate base?

Answer 14

the base (proton acceptor) on the product side of the reaction
