Calculate the pH of 5.8 × 10-8 M HCl. Report your answer to the
hundredths place.What fraction of the total H in this solution is
from the HCl? Report your answer to the hundredths place. The
answer is NOT pH=6.80 and H+=.376 or 37.6 or .37must take water
into consideration thanks

A. Calculate the pH of an HCl solution in pure water that’s
initially 5.0 x 10–8 M. Does the value you obtain appear to follow
the trend you see in Table 2?
B. Calculate the pH of an aqueous solution that’s initially 5.0
x 10–8 M in HCl and 0.10 M in NaCl. Don’t forget that activities
need to be used in the Kw expression but actual
concentrations are called for when balancing positive and negative
charges.

What is the pH of a 0.50 M solution of HCl?

What would the pH be of a solution obtained by mixing 0.2 mL 1 M
HCl with 10 mL distilled water? What would the pH be of a solution
obtained by mixing 0.2 mL 1 M HCl with 10 nM NaOH (aq)? How do
these values compare to the pH values you obtained when you added
acid to your buffers?
