The ph of a solution is 8.05 ± 0.02. "what is the concentration of h in the solution and its absolute error

pH is equivalent to the negative log of the concentration of H in molarity, that is:

pH = - log [H]

so the concentration is:

8.05 = - log [H]

[H] = 8.91 x 10^-9 M

the absolute error is:

8.07 = - log [H’]

[H’] = 8.51 x 10^-9 M

absolute error = 8.91 x 10^-9 M - 8.51 x 10^-9 M = 0.4 x 10^-9 M

Therefore:

8.91 x 10^-9 M ± 0.4 x 10^-9 M

if you're asking what comes out, it's steam.
