Question

Identify the Bronsted acid and base in each of the following equations: Please show all work on how you got the answer so I can understand.

HNO₃ + H₂O

Answer 1

Bronsted acid is a proton donor

Bronsted base is a proton acceptor

HNO₃ + H₂O H₃O⁺ + NO₃^-

HNO₃ is Bronsted acid because it is proton donor (gives a proton to H₂O)

H₂O is Bronsted base because it is proton acceptor (gains a proton from HNO₃)

H₃O⁺is Bronsted acid because it is proton donor (gives a proton to NO3^-)

NO₃^- is Bronsted base because it is proton acceptor (gains a proton from H₃O⁺)

NH₄⁺+ HS^- H₂S + NH₃

NH4⁺ is Bronsted acid because it is proton donor (gives a proton to HS^-)

HS^- is Bronsted base because it is proton acceptor (gains a proton from NH₄⁺)

H₂S is Bronsted acid because it is proton donor (gives a proton to NH₃)

NH₃ is Bronsted base because it is proton acceptor (gains a proton from H₂S)

CH₄ + CD₃^- HCD₃ + CH₃^-

CH₄ is Bronsted acid because it is proton donor (gives a proton to HCD₃^-)

CD₃^- is Bronsted base because it is proton acceptor (gains a proton from CH₄)

HCD₃ is Bronsted acid because it is proton donor (gives a proton to CH₃^-)

CH₃^- is Bronsted base because it is proton acceptor (gains a proton from HCD₃)
