Monoprotic Acids and Bases

Question 1

Define a monoprotic acid?

Answer 1

Is an acid that donates one hydrogen ion or proton per molecule when it dissociates in water

Question 2

Give an example of a monoprotic acid and its dissociation in water.

Answer 2

HNO3(aq) + H2O(l) –> H3O+(aq) + NO3-(aq)

Question 3

Explain the concept of pH in relation to a monoprotic acid.

Answer 3

• All single-hydrogen acids are monoprotic but not all monoprotic acids contain only a single hydrogen because only one hydrogen is released, the pH calculation for a monoprotic acid is straightforward and predictable.
  -The pH of a monoprotic acid can be calculated using the formula pH = -log10[H+], where [H+] is the concentration of hydrogen ions in moles per liter. If you need to find the pH of a base use the formula pH = 14 + log10[OH-]. The general equation for a monoprotic acid in aqueous solution is HA(aq) + A-(aq)

Question 4

How does a monoprotic base differ from a monoprotic acid?

Answer 4

A monoprotic acid is an acid that can donate only one proton. A monoprotic base can only accept one proton.

Question 5

Provide an example of a monoprotic base and its reaction in water?

Answer 5

CH3
