Question

Calculate the pH of 5.2 × 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.

Answer #1

Calculate the pH of 7.0 × 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.

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

What is the pH of a 8.2× 10–8 M solution of HCl(aq) at 25 °C?
Report your answer to the hundredths place.

Calculate the pH of 4.6 ✕ 10−8 M HClO4. What fraction of the
total H+ in this solution is derived from dissociation of
water?

1. Calculate the pH (pH = –log[H+ ]) of the following solutions:
a. 0.10 M HCl
solution b. 0.010 M HCl
solution c. 0.0010 M HCl
solution d. 0.10 M NaOH
solution e. 0.010 M
NaOH
solution f. 0.0010 M NaOH
solution g. 0.10 M HC2H3O2 solution (Ka = 1.8 x 10 –5 )
h. 0.10 M NH3 solution (Kb = 1.8 x 10–5 )

What is the pH of 5.1× 10–3 M HCl?
What is the pH of 8× 10–8 M HCl?

Determine the pH of each solution.
8.40×10−2 M HClO4
a solution that is 5.2×10−2 M in HClO4 and
4.7×10−2 Min HCl
a solution that is 1.06% HCl by mass (Assume a density of 1.01
g/mL for the solution.)

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.
