Acids And Bases

Question 1

Define bronsted Lowry acid and conjugate base

Answer 1

Bronstead Lowry acid donates one mole of a proton and conjugate base is the acid that donates the proton

Question 2

Define bronstead lowry base and conjugate acid

Answer 2

BL base is A proton accepter and conjugate acid is the base that gained a proton and becomes positive

Question 3

Define strong acid

Answer 3

An acid that the H+ fully dissociates in water
A proton donor

Question 4

Define weak acid

Answer 4

An acid that the h+ partially dissociate in water

Question 5

Define a strong base

Answer 5

Substance that fully dissociates into OH- ions in water
A proton acceptor

Question 6

Define a weak base

Answer 6

A substance that partially dissociates into OH- ions in eater

Question 7

Define an alkali

Answer 7

Base which dissolves in water and releases oh- ions

Question 8

Reaction of acid + metal

Answer 8

• forms salt and hydrogen
• ionic equation example:
  2H+ + Zn = Zn2+ + h2

Question 9

Reaction of acid + carbonate

Answer 9

• forms co2, h20 and salt
  For example
  2H+ + CuCO3= Cu2+ + H20 and CO2

Question 10

Reaction of acid + metal oxides

Answer 10

• metal oxides are a base so form salt and water
• 2H+ + MgO = Mg2+ + h2o
