Among the following Ka values, which represents the strongest acid?
A. Ka = 1.2 x 10-3
B. Ka = 3.4 x 10-5
C. Ka = 8.7 x 10-8
D. Ka = 5.8 x 10-10
would the answer be A? please explain, don't just give me the answer.
Yes, A is the correct answer.
In the acid, HA, it ionizes as
HA ==> H^+ + A^-
Ka = (H^+)(A^-)/(HA)
The acidity of a solution depends upon the (H^+) so the higher that is the stronger the acid. Look at Ka values. If Ka is large then the numerator (the H^+) is larger. For the choices given,
A is stronger than B which is stronger than C which is stronger than D.
Well, well, well, acidity, my favorite topic! So, you're trying to find the strongest acid among these Ka values, huh? Alright, let's break it down.
Firstly, Ka represents the acid dissociation constant, which tells us how easily an acid donates its proton. The higher the Ka value, the stronger the acid!
So, let's look at the values. In this case, A has the highest Ka value of 1.2 x 10-3. Is it the strongest acid? Almost there! But hold on, let's compare it to the others.
B has a slightly lower Ka value, 3.4 x 10-5. It's not as strong as A, but we're not winning any acidity contests with this one.
Now, C has Ka = 8.7 x 10-8. Hmm, it seems we're going in the wrong direction here. This value is even smaller than B. So, C is not the strongest acid.
Lastly, D has the smallest Ka value of 5.8 x 10-10. Sorry, D, but you're the weakest link!
Therefore, after carefully analyzing all the options, we can conclude that A, with its highest Ka value, represents the strongest acid. Well done, A! You beat the others in the acidity game!
To determine which Ka value represents the strongest acid, we need to understand that Ka represents the acid dissociation constant. The larger the Ka value, the stronger the acid.
Using the given values:
A. Ka = 1.2 x 10^(-3)
B. Ka = 3.4 x 10^(-5)
C. Ka = 8.7 x 10^(-8)
D. Ka = 5.8 x 10^(-10)
We can see that D has the smallest Ka value (5.8 x 10^(-10)). Therefore, D represents the strongest acid.
Therefore, the correct answer is D.
To determine which Ka value represents the strongest acid, we need to understand that Ka is the acid dissociation constant. It measures the extent to which an acid dissociates or ionizes in water to form hydrogen ions (H+).
The larger the Ka value, the stronger the acid. This is because a higher Ka indicates a greater degree of ionization, which means more hydrogen ions are formed.
Let's compare the given Ka values:
A. Ka = 1.2 x 10-3
B. Ka = 3.4 x 10-5
C. Ka = 8.7 x 10-8
D. Ka = 5.8 x 10-10
Comparing these values, we can see that the Ka value for option A, 1.2 x 10-3, is the largest among the given options. Therefore, option A represents the strongest acid because it has the highest Ka value.
