Acids and Bases - Bronsted-Lowry Model

Question 1

bronsted-lowry acids and bases

Answer 1

• acids are H+ (proton) donors (not really different from Arrhenius Definition)
• bases are H+ (proton) acceptors (can deal with organic amines)
• ammonia NH3 reacts with HCl
• NH3 + HCl -> NH4+ + Cl-
• base + acid -> conjugate acid + conjugate base

Question 2

in the following acid-base reaction, NH4+ is the _____

H2PO4-(aq) + NH3(aq) -> HPO4 2-(aq) + NH4+(aq)

Answer 2

• conjugate acid

Question 3

in the following acid-base reaction, H3O+ is the ______

HCl(g) + H2O(l) -> H3O+(aq) + Cl-(aq)

Answer 3

• conjugate acid

Question 4

bronsted-lowry bases are proton ______

Answer 4

• acceptors

Question 5

In the following acid-base reaction H2O is the _______

HCl(g) + H2O(l) -> H3O+(aq) + Cl-(aq)

Answer 5

• base

Question 6

In the following acid-base reaction HCl is the ________

HCl(g) + H2O(l) -> H3O+(aq) + Cl-(aq)

Answer 6

• acid
