acids and bases

Question 1

strong acids definition

Answer 1

strong acids disassociate fully in aqueous solution

Question 2

monoprotic strong acids equation

Answer 2

HCL -> H+ + CL-

HNO3 -> H+ + NO3-

Question 3

Diprotic strong acids equation

Answer 3

H2SO4 -> H+ SO4-

Question 4

HCL + H2O

Answer 4

HCL + H2O -> CL- + H3O+
H3O+ - is a hydronium ion formed by a coordinate bond (pyramidal)

Question 5

weak acid definition

Answer 5

weak acids partially disassociate in aqueous solution

Question 6

monoprotic weak acid equation

Answer 6

CH3OOH <=> CH3COO- + H+

Question 7

What is a bronsted- lowry acid

Answer 7

a proton donor

Question 8

strong base definition

Answer 8

strong bases fully dissociate in an aqueous solution

Question 9

monobasic equation

Answer 9

NaOH -> Na+ + OH-

Question 10

Dibasic equation

Answer 10

Ba(OH)2 -> Ba2+ + 2OH-

Question 11

weak bases definition

Answer 11

NH3 + H2O <=> NH4+ + OH-

Question 12

A Bronsted lowrey base

Answer 12

is a proton acceptor

Question 13

acid / base pairs
CH3COOH + H2O

Answer 13

CH3COOH + H2O <=> CH3COO- + H3O+
acid + base <=> conjugate base of CH3COOH + conjugate acid of water

Question 14

what is the pH scale

Answer 14

measure of the acidity of a solution

Question 15

pH equation

Answer 15

pH = -log10 [H+]

all pH values must be given to 2.d.p

Question 16

the reverse of the pH equation

Answer 16

[H+] = 10-pH
