How do I prepare a 1 M ammonium acetate buffer with a pH of 7. I have solid ammonium acetate, .1 M acetic acid, and 12 M hydrochloric acid. The total volume needs to be 1 liter.

How can I explain patient's pH value given his PaCO2 results in terms of that? Equation CO2 + H2O = H2CO3 = H+  +  HCO3- Patient's results pH = 7.3 PaCO2 = 77 mm Hg HCO3- = 36 mEq/L

Many manufacturers claim that their health care and hair care products are pH balanced or buffered. How would you test their claims?

The pH of a solution is 7, what is the H+ concentration?   Group of answer choices   1 x 10e-7 M 1 x 10e-3 M 1 x 10e-8 M 1 x 10e-9 M

If a patient has a pH of 7.02 which is outside the accepted range what would I administer? NaHCO3 by IV fluid therapy or H2CO3 by IV fluid therapy

The concentration of the conjugate base in 100 mL of 50 mM CH3COOH/CH3COO- (pKa = 4.76) at pH 5.00 is    ______mM. If 100 μL of 1.0 M NaOH is added, the buffer pH is expected to shift to ______    please answer it and explain .

7. You need to prepare an acetate buffer of pH 5.53 from 0.0875 M Acetic acid solution and 2.02 M KOH solution. If you have 725 ml of acetic acid solution, how many milliliters of KOH solution do you need to add to make a buffer of pH 5.53? The pKa of acetic is 4.76

Can you explain the various options and how did you come to the answer? How to determine when something is a weak acid or base or strong acid or base? Is there are any trick?
