Syre-base reaktioner

QuestionAnswer
Hvad er vandsionprodukt? 1*10^-14 (25 grader) ligevægtskonstanten for vand ved 25 grader
Hvad er et puffersystem? Et system, som består af en syre og dens korresponderende base. Denne opløsning, kan bibeholde en PH, selvom der bliver tilsat mere base eller syre
Hvordan udregnes PH i en ikke stærk base? pOH = -log[OH-] PH=14-pOH
Hvordan lyder pufferligningen? PH=Pks+log([B]/[S])
Hvordan lyder Oswalds fortyndinglov? "hvis man fortynder en opløsning, så vil protolyse graden stige"
Hvad er protolysegrad? Den del af den oprindelige mængde syre, der er omdannet til den korresponderende base
Hvordan udregnes pOH i en stærk base? pOH = -log(x*Cb)
Hvad betyder det at syrens styrkekonstant Ks er lille? Syren reagere næsten ikke med vandet. Ligevægten ligger mod venstre.
Hvad betyder det at syrens styrkekonstant Ks er stor? Syren reagere så godt som fuldstændig med vandet Ligevægten ligger mod højre.
Hvad betyder hhv. monohydron, dihydron og trihydron? afgiver hhv. ét (mono.)-, to (di.)- og tre(tri)hydroner
Hvad betyder at styrkeeksponenten er lav? og hvorfor?! styrkeeksponenten udregnes vha. formlen: pKs = -log(Ks) og derfor er syren stærk, når denne er lav, da det er omvendt styrkekonstanten.
Hvad er PH, når man har tit. en svag syre med en stærk base. PH = pKs
Hvordan udregnes alfa, a? a=[H3O+]/Cs
Hvad er en amfolyt? Et stof, som kan reagere med sig selv, fordi den både optræder med en syre og en base. ex vand
Hvad er en titrerkurve? En funktion af volumen og PH udfra et forsøg

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.
