Amphiprotic Species and Their Characteristics

The video tutorial discusses the concept of amphiprotic species in IB Chemistry, explaining that these species can both accept and donate protons, acting as both Bronsted-Lowry acids and bases. It differentiates between amphiprotic and amphoteric species and provides an example question to identify an amphiprotic species. The tutorial concludes that HPO4 2- is the amphiprotic species in the question, as it can donate a proton to become PO4 3- and accept a proton to become H2PO4 -.

What is an amphiprotic species capable of doing?

• Only donating protons

• Only accepting protons

• Both accepting and donating protons

• Neither accepting nor donating protons

How is the term 'amphiprotic' related to 'amphoteric'?

• They are completely unrelated

• They are synonyms

• Amphiprotic is a subset of amphoteric

• Amphoteric is a subset of amphiprotic

What must a species have to be considered amphiprotic?

• A neutron to accept

• A proton to donate

• A neutron

• An electron to donate

Which of the following species is amphiprotic?

• P4O10

• CO3^2-

• HPO4^2-

• Al2O3

What happens to HPO4^2- when it donates a proton?

• It becomes PO4^3-

• It remains unchanged

• It becomes H2PO4^-

• It becomes H3PO4

How can HPO4^2- act as a base?

• By accepting an electron

• By accepting a proton

• By donating an electron

• By donating a neutron

What is the final answer to the multiple-choice question discussed in the video?

• C

• A

• D

• B

Which of the following is NOT a characteristic of an amphiprotic species?

• Can donate an electron

• Can accept a proton

• Can donate a proton

• Can act as both an acid and a base

What is the significance of a species being able to donate a proton?

• It can only act as an acid

• It can act as both an acid and a base

• It can only act as a base

• It cannot act as either

Why is it important for a species to have a proton to be amphiprotic?

• To accept it and act as an acid

• To donate it and act as a base

• To donate it and act as an acid

• To accept it and act as a base
