Example Question #11 : Acid Base Chemistry
What is a triprotic acid?
An acid with one ionizable hydrogen
An acid that accepts an electron pair
An acid with two ionizable hydrogens
An acid that donates an electron pair
An acid with three ionizable hydrogens
An acid with three ionizable hydrogens
Acids have hydrogen ions and balanced charges. "Tri" tells us that the acid has three potential hydrogen ions. Once ionized, a hydrogen turns into a proton, hence, protic. An example of a triprotic acid is phosphoric acid
Example Question #12 : Acid Base Chemistry
What is a monoprotic acid?
An acid with three ionizable hydrogens
An acid with two ionizable hydrogens
A really weak base
An acid with one ionizable hydrogen
Any acid with more than 2 ionizable hydrogens
An acid with one ionizable hydrogen
Acids have hydrogens that can dissociate into solution. In this case, the word "mono" tells us that there is only one potential hydrogen ion in that acid; so only one hydrogen ion can be ionized from that acid. A diprotic acid, such as has two ionizable hydrogens.
Example Question #12 : Acid Base Chemistry
What is a polyprotic acid?
An acid with three ionizable hydrogens
An acid with one ionizable hydrogen
An acid with two ionizable hydrogens
Any acid with more than two ionizable hydrogens
An acid that increases the concentration of hydrogen ions in a solution
Any acid with more than two ionizable hydrogens
By definition, a polyprotic acid is one that has more than two ionizable hydrogens.
Example Question #13 : Definitions Of Acids And Bases
Which of the following substances are amphoteric?
Remember: amphoteric means that the substance can act as either an acid or a base. Using the Bronsted-Lowry definition of acids and bases (acids donate hydrogens and bases accept hydrogens) we find that is the only compound that can give up a hydrogen (and be left with
), or accept a hydrogen (and become
).
Example Question #13 : Acid Base Chemistry
According to the Arrhenius definition __________.
bases accept electron pairs
acids are hydroxide donors
acids increase the concentration of hydroxide ions in a solution
acids accept electron pairs
bases increase the concentration of hydroxide ions in a solution
bases increase the concentration of hydroxide ions in a solution
According to the Arrhenius definition, bases increase the concentration of hydroxide ions in a solution.
Example Question #14 : Acid Base Chemistry
According to the Arrhenius definition, acids __________.
Acids increase the concentration of hydroxide ions in a solution
Acids are proton acceptors
Acids are hydroxide donors
Acids are hydrogen donors
Acids increase the concentration of hydrogen ions in a solution
Acids increase the concentration of hydrogen ions in a solution
According to the Arrhenius definition, acids increase the concentration of hydrogen ions in a solution.
Example Question #16 : Acids And Bases
What is the Bronsted-Lowry definition of acids?
Acids are hydrogen acceptors
Acids are electron pair donors
Acids are amphoteric
Acids are electron pair acceptors
Acids are hydrogen donors
Acids are hydrogen donors
According to the Bronsted-Lowry definition, acids are hydrogen donors.
Example Question #15 : Acid Base Chemistry
What is the definition of a Bronsted-Lowry base?
Hydrogen acceptors
Electron pair donors
Increases the concentration of hydrogen ions in a solution
Hydrogen donors
Electron pair acceptors
Hydrogen acceptors
According to the Bronsted-Lowry definition, bases are hydrogen acceptors.
Example Question #1 : Identifying Acids And Bases
Which of the following will result when a base and an acid react with one another?
Acids are able to donate protons whereas bases can donate hydroxyl groups. The general acid-base reaction will be a double-replacement reaction in which the proton of the acid binds the hydroxide of thee base, and the cation of the base binds the anion of the acid to form a salt. The products of this reaction are a salt and water. This is called a neutralization reaction.
Example Question #1 : Identifying Acids And Bases
What is the conjugate base of nitric acid ?
Every acid has a conjugate base and every base has a conjugate acid. For any acid, the conjugate base is the negatively charged ion that is created when the acid dissociates in solution.
Nitric acid dissociates in solution based on the following reaction:
The nitrate ion, , is created following the dissociation of nitric acid. This means that the nitrate ion is the conjugate base of nitric acid.
