hram777 [196]

Answer:

The correct answer is B. A client who has increasing serum ammonia levels due to liver cirrhosis

What is the pH if 20 mL of pH = 2 solution is diluted to a final volume of 600 mL?
Mashutka [201]

Explanation:

Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge.  pH measures how basic or acidic a water-based solutions are, with a formula for pH is

pH = -log[H+].

...where pH is -base 10 log of the concentration of hydrogen ions within the solution.

Initial volume= 20 mL

Final volume= 600 mL

# of dilutions= \frac{600}{20} = 30

for a pH 2= [H+]= 10^{=2}

∴ [H+]=  \frac{10^{-2}}{30} = 3.333 * 10^{-4}

and pH is an antilog of [H+]= - log \frac{10^{-2}}{30} = 3.333 * 10^{-4}

∴pH = 3.47
