1. Acids + Alkalis

Question 1

what is produced when a non metal oxide is dissolved in water

Answer 1

acid

Question 2

what is acid rain

Answer 2

non metal oxide gases mixing with rain

Question 3

what is CH3COOH

Answer 3

ethanoic acid

Question 4

what is produced when a metal oxide or a metal hydroxide is dissolved in water

Answer 4

an alkali

Question 5

what happens to the pH of the water when metal oxides or hydroxides that are insoluble are added

Answer 5

the metal oxide/hydroxide cannot dissolve and therefore cannot change the pH of the water. it’s like putting a lego brick in water, it can’t dissolve therefore the water stays the same Nothing

Question 6

what is the equation of the breakdown of water molecules into ions

Answer 6

H2O ↔️ H+ and OH-

the reaction can go both ways

Question 7

what is the concentration of ions in an acid

Answer 7

H+ > OH-

Question 8

what is the ion concentration in an alkali

Answer 8

H+ < OH-

Question 9

what is the ion concentration in a neutral (water)

Answer 9

H+ = OH-

Question 10

what happens to the pH when acid is diluted

Answer 10

it goes up

Question 11

what happens to the pH when alkali is diluted

Answer 11

it goes down

Question 12

what happens to the pH when a neutral is diluted

Answer 12

it stays the same

Question 13

What is HCl?

Answer 13

Hydrochloric Acid

Question 14

What is HNO3

Answer 14

Nitric Acid

Question 15
