If the ph of a solution is 2.78 with an absolute uncertainty of ±0.05, what is the latex: \left[h^+\right][ h + ] and its uncertainty?

[H⁺] = 16.6 (±1.9) x10⁻⁴ M

Explanation:

The pH is defined as:

So we can calculate [H⁺]:

[H⁺] = 1.66x10⁻³ M

The relative uncertainty in [H⁺] is

Thus the uncertainty in the concentration is:

1.66x10⁻³ M * 0.115 = 1.91x10⁻⁴ M
