Question 1

What are acids?

Answer 1

Compounds that, when dissolved in water, release H+ ions

Question 2

Answer 2

Sulfuric acid(H2SO4), nitric acid(HNO3), and hydrochloric acid(HCl)

Question 3

What are Alkalis?

Answer 3

Compounds that, when dissolved in water, release OH- ions

Question 4

What type of scale is the PH scale and what is the definition of it?

Answer 4

It is a logarithmic scale, which means it is that an increase or decrease of 1 indicates there is 10x less ore more H+ ions in the solution

Question 5

Name some strong acids and why they are strong

Answer 5

Sulfuric acid, nitric acid, and hydrochloric acid. They are strong because they completely ionise

Question 6

Name some weak acids and what makes them weak

Answer 6

Ethanoic acid, citric acid, and carbonic acid. They are weak because they are only partially ionised
