Acids and stuff

Question 1

What is a monobasic acid?

Answer 1

A monobasic acid is an acid that can release on proton per molecule.

Question 2

What is a dibasic acid?

Answer 2

A dibasic acid is an acid that can release two protons per molecule.

H2SO4 is a dibasic acid because each molecule can release 2 protons. This is done in two stages.

H2SO4—> H+ + HSO4-
HSO4- H+ + SO4^2-

Question 3

What is a tribasic acid?

Answer 3

An acid in which each molecule can release 3 protons.

Question 4

Show the reaction between HCl and water in a simplified form and another form.

Answer 4

HCl(aq) —-> H+(aq) + Cl-(aq)

HCl(aq) + H2O(l) —–> H3O+(aq) + Cl-(aq)

Question 5

What is an acid-base pair?

Answer 5

An acid-base pair is a set of two species that transform into each other by gain or loss of a proton.

Question 6

Describe in the following:

HNO2(aq) + H2O(l) H3O+(aq) + NO2-(aq)

Which is the acid/conjugate acid and base/conjugate base

Answer 6

HNO2 is the acid and its conjugate base is NO2-

H2O is the base and its conjugate acid is H3O+
