Question 1

neutralisation reactions 1/2

Answer 1

CH3COOH + NaOH = CH3COONa + H2O

Question 2

CH3COOH + NaOH = CH3COONa + H2O

Answer 2

ethanoic acid + sodium hydroxide = sodium ethanoate + water

neutralisation reactions 1/2

Question 3

neutralisation reactions 2/2

Answer 3

2CH3COOH + Na2CO3 = 2CH3COONa + CO2 + H2O

Question 4

2CH3COOH + Na2CO3 = 2CH3COONa + CO2 + H2O

Answer 4

ethanoic acid + sodium carbonate = sodium ethanoate + carbon dioxide + water
(neutralisation reactions 2/2)

Question 5

reaction with metal

Answer 5

2CH3COOH + 2Na = 2CH3COONa + H2

Question 6

2CH3COOH + 2Na = 2CH3COONa + H2

Answer 6

ethanoic acid + sodium = sodium ethanoate + hydrogen

reaction with metal

Question 7

limescale (buildup in kettles)

Answer 7

2CH3COOH + CaCO3 = (CH3COO)2Ca + CO2 + H2O

Question 8

2CH3COOH + CaCO3 = (CH3COO)2Ca + CO2 + H2O

Answer 8

ethanoic acid + calcium carbonate = calcium ethanoate + carbon dioxide + water
(limescale (buildup in kettles))

Question 9

acid hydrolysis

Answer 9

H-C=O-O-CH2-CH3 + H2O = H-C=O-OH + H-O-CH2-CH3

Question 10

H - C= O - O - CH2 - CH3 + H2O = H - C = O - OH + H-O-CH2-CH3

Answer 10

ethyl methanoate + water = methanoic acid + ethanol

acid hydrolysis

Question 11

example of saponification

Answer 11

CH3-C=O-O-CH2-CH3 + NaOH = CH3-C=O-O-Na + HO-CH2-CH3

Question 12

CH3-C=O-O-CH2-CH3 + NaOH = CH3-C=O-O-Na + HO-CH2-CH3

Answer 12

ethyl ethanoate + sodium hydroxide = sodium ethanoate + ethanol
(example of saponification)
