Chem Unit 9 Test

Flashcards for the general knowledge section of the chem unit 9 test.

QuestionAnswer
What is Acid-Base Titration? Procedure used to determine the concentration of an acid or base using a standard acid or base.
What is a Standard Solution? Solution whose concentration is known precisely. A standard solution is used to neutralize an acid/base of unknown concentration.
What does an acid + base make? H2O + salt
What is the equivalence point? The equivalence point point in a titration where mol H+ = mol OH- (neutralization). (Acid = base)
What is an indicator? Equivalence points can be detected using an acid-base indicator. Indicators change color at certain pH levels.
What is an endpoint during titration? Point in titration where the indicator changes color.
What is a hydronium ion? H3O+
What is a strong acid? Acids that dissociate nearly completely.
What is a weak acid? Acids that do not dissociate to great extent.
What does pOH stand for? “power of the hydroxide ion”
What do acids do? Donates protons (H+)
What do bases do? Accepts protons.
What is a conjugate base? What's left of the acid after it has donated a proton.
what is a conjugate acid? What's formed after the base has accepted a proton.
What does Amphoteric? A subject that can act as both an acid or a base is called amphoteric. H2O is an example of this.
What does brackets represent? Brackets around a species represents concentration in molarity (M).
What is the Kw constant? [H+][OH-] = 1.0 * 10^-14. Kw is called the “water dissociation constant”
Neutral solution? [H+] = [OH-]
Acidic solution? [H+] > [OH-]
Basic solution? [H+] < [OH-]
What does pH stand for? “power of the Hydrogen ion”
What is the pH scale based on? The pH scale is a logarithmic scale based on the power of 10 (log10)
What is molarity? The number of moles of solute dissolved in total liters of solution. Expressed in units of mol/L or M.
What color does cabbage turn distilled water? Purple
What is the tool used for titration called? A buret
When the solution containing phenolphthalein turns pink during titration, is it being mixed with an acid or a base? A base, during a titration lab you go from acid to base.
Acid reacts with many ____ to produce ____ . metals, H2 gas
Acid reacts with ____ to produce ____ . Carbonates, CO2 gas

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.
