chapter 20 & 21

Base Compound that produces hydroxide ions when dissolved in water
Hydroxide ion (OH) water molecule that gains a hydrogen ion ecomes a positively charged hydronium ion ion (h3o)
self-ionization two water molecules produces ions of water to become changed into the form of ions, as by dissolving.
ion product constant for water The product of the concentrations of the hydrogen ions and hydroxide ions in water
acidic solution
acid compound that produces hydrogen ions when dissolved in water
natural solution pH is a measure of the acidity or basicity of a solution
Basic solution one in which [H+] is less than [OH-]. Therefore, the [H+] of a basic solution is less than 1.0 X 10"7M
Monoprotic acids acids that contain one ionizable hydrogen such as nitric acid
diprotic acids two ionizable hydrogens sulfuric acid
triprotic acids phosphoric acid
hydrogen-ion donor an acid according to bronsted lowry theory
hydrogen - ion acceptor Any substance that is capable of becoming reduced and accepting hydrogen atoms
conjugate base the particle that remains when an acid has donated a hydrogen ion oh- is the conjugate base of acid water
conjugate acid the particle formed when a base gains a hydrogen ion
conjugate acid base pair two substances that are related by the loss or gain of a single hydrogen ion oh- is the conjugate acid-base pair
amphoteric a substance that can be act as both an acid and a base, water is amphoteric
Lewis acid any substance that can accept a pair of electrons to form a covalent bond
Lewis base any substance that can donate a pair of electrons to form a covalent bond
strong acids an acid that is completely ionized in aqueous solution
weak acids an acid that is only slightly ionized in aqueous solution
acid dissociation constant the ratio of the concentration of the dissociated form of an acid to the undissociated from stronger acids have larger k values than weaker acids
strong bases a base that completetely dissociates into metal ions and hydroxide ions in aqueous solution
weak base a base that does not dissociated completely in aqeous solution
base dissociation constant the ratio of the concentration of the dissociated form of a base to the undissocited form
neutralization reactions a reaction in which an acid and a base react in an aqueous solution to produce a salt and water
standard solution a solution of known concentration used in carrying out a titration
titration method used to determine the concentration of a solution
end point the point in a titration at which netrutrazation is achieved
equivalent the amount of an acid that can give one mole of hydrogen ions
gram equivalent mass the mass of one equivalent of a substance
normality (N) the concentration of a solution expressed as the number of equivalents of solute in 1 litter of solution
equlvance point the point in a titration at which the number of equivalents of acid and base are equal
ph pH is a measure of hydrogen ion concentration
ph meters

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.
