Acids and Bases

Vocabulary for Acids and Bases

Alkaline Means the same as BASE. A solution in which there are more OH- ions than H+ ions
Arrhenius Acid A chemical compound that increases the concentration of hydrogen ions, H+, in aqueous solution
Arrhenius Base A substance that increases the concentration of hydroxide ions, OH-, in aqueous solution
Binary Acid An acid that contains only two different elements: hydrogen and one of the more-electronegative elements
Oxyacid An acid that is a compound of hydrogen, oxygen, and a third element, usually a non-metal
Strong Acid An acid that ionizes completely in aqueous solution
Weak Acid An acid that is a weak electrolyte
Amphoteric Any species that can react as either an acid or a base
Bronsted-Lowry Acid A molecule or ion that is a proton donor
Bronsted-Lowry Acid-Base Reaction The transfer of protons from one reactant (the acid) to another (the base)
Bronsted-Lowry Base A molecule or ion that is a proton acceptor
Conjugate Acid The species that is formed when a Bronsted-lowry base gains a proton
Conjugate Base The species that remains after a Bronsted-Lowry acid has given up a proton
Diprotic Acid An acid that can donate two protons per molecule
Monoprotic Acid An acid that can donate only one proton (hydrogen ion) per molecule
Polyprotic Acid An acid that can donate more than one proton per molecule
Triprotic Acid An acid able to donate three protons per molecule
pH The negative of the common logarithm of the hydronium ion concentration of a solution
pOH The negative of the common logarithm of the hydroxide ion concentration of a solution
Self-Ionization of Water A process in which two water molecules produce a hydronium ion and a hydroxide ion by transfer of a proton
Neutralization The reaction of hydronium ions and hydroxide ions to form water molecules
Salt An ionic compound composed of a cation and the aniion from an acid; an ionic compound composed of a cation from a base and an anion from an acid
End Point The point in a titration at which an indicator changes color
Equivilance Point The point at which the two solutions used in a titration are present in chemically equivalent amounts
Acid-Base Indicator A compound whose color is sensitive to pH
pH Meter A device used to determine the pH of a solution by measuring the voltage between the two electrodes that are placed in the solution
Titration The controlled addition and measurement of the amount of a solution of known concentration required to react completely with a measured amount of a solution of unknown concentration
Neutral h

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
