what is the concentration of [H+} in molars, millimolars, and micromolars for a solution of pH 5?
In case you need this information:
milli= 10^-3
micro=10^-6
Thank you.
[H+] is 10^-5 moles/liter (10^-5 molar) for pH = 5
That would be 10^-2 millimolar or 10 micromolar. Those terms are much less often used.
To determine the concentration of [H+] in molars, millimolars, and micromolars for a solution of pH 5, we need to use the equation:
[H+] = 10^(-pH)
First, let's calculate the concentration in molars:
[H+] (in molars) = 10^(-pH)
[H+] (in molars) = 10^(-5)
Next, let's convert the concentration from molars to millimolars:
[H+] (in millimolars) = [H+] (in molars) * 1000
[H+] (in millimolars) = 10^(-5) * 1000
Finally, let's convert the concentration from millimolars to micromolars:
[H+] (in micromolars) = [H+] (in millimolars) * 1000
[H+] (in micromolars) = (10^(-5) * 1000) * 1000
Using the given values:
[H+] (in molars) = 10^(-5) = 0.00001 M
[H+] (in millimolars) = 10^(-5) * 1000 = 0.01 mM
[H+] (in micromolars) = (10^(-5) * 1000) * 1000 = 10 μM
Therefore, for a solution with a pH of 5, the concentration of [H+] is approximately 0.00001 M (molars), 0.01 mM (millimolars), and 10 μM (micromolars).
