. Answer the following questions and attach with your prelab write-up. a) What is the [H+ ] in M, mM, and µM in a solution that

has pH 5.5? b) Which formula would you use if you are to calculate the ratio of dissociated vs. un-dissociated forms c) When sufficient H+ is added to lower the pH by one unit, what is the corresponding increase in [H+ ]? Explain with example. d) Calculate the pH of 2.56x10-3 M monobasic base solution (assuming complete ionization) e) Identify sources of acid and base components of the following salts: i) Sodium Chloride ii) Potassium Acetate iii) Ammonium Chloride

Answer:

[H+]=3.2x10^-6 M 3.2 x 10^-3 mM 3.2 uM

Explanation:

b. Doesn't realy matter but uM would not use exponent of 10

c. 10 times

d. log base 10 2.56 =0.41 log 10^-3 = -3 -3+0.41= -2.59=pH2.59

e. Sodium Chloride HCl & NaOH

KOH & Acidic acid

NH4OH & HCl
