Question

Four acids are analyzed and their Ka values are determined. Which of the following values represents the strongest acid?

Answer 1

what are the choices?

Answer 2

please give full info about question @Olea0513

Answer 3

Ka = 2.2 × 10−13

Ka = 6.2 × 10−8

Ka = 1.7 × 10−5

Ka = 1.2 × 10−

Answer 4

hmm... thats not so clear @Olea0513

Answer 5

thats the question and the choices and im so stumped :(

Answer 6

The one with the lowest numerical value has the highest pH. pH represents the number of hydrogen ions in the given substance. The lower the pH the more acidic the substance. The general idea is that something with a pH of 1 is highly acidic, 2 a little less acidic and so on, until you reach 7 which is neutral (water). Above 7, substances are no longer acidic, but 'basic.'

so which one do you think it is..?

Answer 7

strong acids have Ka values greater then one

Answer 8

so values greater than one is a indication of strong acid

Answer 9

so the value greater then 1.2 & 1.7 or 2.2 is the strongest acid ??...

Answer 10

hmm..
which is the biggest value

Answer 11

the lowest values are more acidic than the higher ones, so say it was 1.5 and 1.6, 1.5 is more acidic by a little bit

Answer 12

OH ! SO 1.2 WAS MORE ACIDIC (:

Answer 13

yep, should be. make sure to close your question when your done.

Answer 14

no

Answer 15

wait
those are for pH values @Olea0513 @felipecasal

Answer 16

yeah isnt that what their going for?

Answer 17

hmm..
Ka is dissociation constant for weak acids
