Find the hydrogen ion concentration for Ammonia, with a pH of 11.0. Hint: pH=−log[H+].
________moles per liter
so the log of the concentration is ... -11.0
logarithms are exponents
... for "common" logs (no base given), the base is 10
[H+] = 10^-11
Well, well, well! Looks like we have a chemistry question here. Don't worry, I'll try not to make any "basic" jokes.
Now, we know that the pH is 11.0 and pH is defined as the negative logarithm (base 10) of the hydrogen ion concentration ([H+]). So, all we need to do is reverse this equation.
Taking the antilog (10^x) of both sides, we get:
[H+] = 10^(-pH)
Plugging in the pH value of 11.0, we get:
[H+] = 10^(-11.0)
Alright, get ready for a big scientific calculation! Drum roll, please... *Ba dum tss*
The hydrogen ion concentration for ammonia is approximately 0.0000000001 moles per liter. Whoa, that's quite a small number! I hope it doesn't make ammonia feel too "basic".
To find the hydrogen ion concentration ([H+]) for a given pH of 11.0, we need to use the relationship between pH and [H+], which is defined as:
pH = -log[H+]
First, let's convert the given pH value to a hydrogen ion concentration:
pH = 11.0
Taking the negative logarithm of both sides, we have:
-log[H+] = 11.0
Now, rearranging the equation to solve for [H+], we get:
[H+] = 10^(-pH)
Substituting the given pH value into the equation, we have:
[H+] = 10^(-11.0)
Calculating this value, we find:
[H+] ≈ 7.94 x 10^(-12) moles per liter
Therefore, the hydrogen ion concentration for Ammonia, with a pH of 11.0, is approximately 7.94 x 10^(-12) moles per liter.
To find the hydrogen ion concentration ([H+]) for Ammonia with a pH of 11.0, we can use the equation: pH = -log[H+].
In this equation, pH represents the negative logarithm of the hydrogen ion concentration ([H+]).
First, we rearrange the equation to solve for [H+]. Taking the negative logarithm of both sides gives:
[H+] = 10^(-pH)
Now, substitute the given pH value of 11.0 into the equation:
[H+] = 10^(-11.0)
Using a calculator, evaluate 10^(-11.0):
[H+] ≈ 1.0 × 10^(-11) moles per liter
Therefore, the hydrogen ion concentration for Ammonia, with a pH of 11.0, is approximately 1.0 × 10^(-11) moles per liter.
