Acid and Bases

Question 1

Bronsted Lowry Acid

Answer 1

Anything that is capable of donating a proton

Question 2

Bronsted Lowry Base

Answer 2

Any species that is capable of accepting a proton

[+1 ]requires lone pair of electrons to bond to H+

Question 3

Ampotheric

Answer 3

Acts as both acid and base e.g- Water

Question 4

Strong acid

Answer 4

good proton donor

HCL,HBr, HI,

Question 5

Weak acid

Answer 5

poor proton donor

Question 6

Strong base

Answer 6

good proton acceptor

e.g- Hydroxides

Question 7

Weak base

Answer 7

poor proton acceptor

e.g- Neutral nitrogen/ammonia

Question 8

Conjugate Base

NH3 + H2O → NH+4 + OH-

Answer 8

Species formed after an acid donates a proton

OH-

Question 9

Conjugate Acid

NH3(g)+H2O(l)→NH+4(aq) + OH-(aq)

Answer 9

Species formed after a base accepts a proton

NH+4
