If you add 2 liters of .45% NaCl to 36 liters of blood that has a pH balance of 7.44, what will the new pH be?

To determine the new pH of the blood solution after adding 2 liters of 0.45% NaCl, we need to consider the properties and effects of NaCl and its dilution on pH.

1. Calculate the initial total volume of the blood solution:
36 liters (initial blood volume) + 2 liters (added NaCl) = 38 liters (total volume)

2. Determine the concentration of NaCl in the added solution:
0.45% NaCl means there are 0.45 grams of NaCl in every 100 milliliters (0.1 liters) of solution. Therefore, 1 liter of the NaCl solution contains 4.5 grams of NaCl:
0.45 grams/0.1 liter * 1 liter = 4.5 grams/1 liter = 4.5 g/L

3. Calculate the amount of NaCl added to the blood solution:
To calculate this, we need to convert the concentration to the total amount added:
4.5 g/L * 2 liters = 9 grams of NaCl

4. Consider the effect of NaCl on pH:
NaCl is a neutral salt and does not directly affect the pH of a solution. Hence, adding NaCl to the blood solution will not change its pH.

Therefore, the new pH will remain unchanged at 7.44.
