Flashcards in C21 Terms Deck (28):
The cation formed by the self ionization of water
The anion formed by the self ionization of water.
The state of any two-way process In which the concentration of particles remain relatively constant but the identity of the individual particles constantly changes.
Any substance that donates hydrogen ions.
Any substance that accepts hydrogen ions.
A model of acids and bases in which acid compounds form hydronium ions in aqueous solutions and bases form hydroxide ions in aqueous solutions.
A model of acids and bases that defines acidity and alkalinity based on hydrogen ion transfer. Acids donate hydrogen ions and bases accept hydrogen ions.
An acid that can donate only one hydrogen atom
An acid of three or more atoms
The proton acceptor produced after a Brønsted-Lowry acid donates a proton.
The proton acceptor produced after a Brønsted-Lowry acid donates a proton
Any ionic compound that could be produced by the combination of a base cation and an acid anion in a neutralization reaction.
A reaction between an acid and a base. In aqueous solutions the products are a salt and water.
A scale that indicates the acidity of a solution.
Having a pH value greater than 7
Any substance that turns a specific color in a solution with a particular pH.
An instrument designed to measure the pH of a solution.
Describe how water molecules can hydrate various substances.
They smash and wedge the other molecules off of the other substance and then surround them.
Describe the two ionization reactions that occur in pure water.
In the first one a hydrogen atom is transferred to a water molecule. In the second the exact opposite happens.
Does a reaction involving an acid and a base have to take place in a water environment?
State the general properties of water-soluble acids discussed in this section.
What class of compounds are salts?
In water solutions what occurs in every neutralization reaction?
How do you know when an insoluble salt is formed by an acid base neutralization?
What is a sting acid? Why is an acids strength not related to its concentration?
An acid with a low pH. Because the strength can vary.
In what two ways may various compounds act as strong bases?
They can absorb electrons. Idk.
How is the acidity or alkalinity of a solution measure?
With the pH scale.
