Calculate the PH of a 1.0x10^-1 M solution of HI. Be sure your answer has the correct number of significant figures.
The pH of a hydrogen halide solution like HI can be calculated using the formula:
pH = -log[H+]
Given that the concentration of HI is 1.0x10^-1 M, this means the concentration of H+ ions in the solution is also 1.0x10^-1 M.
Thus, the pH can be calculated as:
pH = -log(1.0x10^-1)
pH = -(-1)
pH = 1
Therefore, the pH of a 1.0x10^-1 M solution of HI is 1.
