1. A patient blood sample has a pH of 7.40 at 25 °C. This questions has three portions. (10 pts) a) Calculate the sample H30* concentration (4pts) b) Determine the OH concentration (4 pts) c) Is the sample is acidic or basic? (2 pts)

Answers

1)

PH = - log [H+]

given PH = 7.4 there fore

[H+] = 10-PH = 10-(7.4) = 3.98x10-8

[H+] = 3.98x10-8

2)

POH = 14 - PH

POH = 14 - 7.4 = 6.6

POH = - log [OH-]

[OH-] = 10-POH = 10-(7.4) = 2.51 x 10-7

[OH-] = 2.51 x 10-7

3)

In the scale of PH 0 to 14

PH is 7 is nuetral

less than 7 it is acid

more than 7 it is basic

so give PH is 7.4 so that is basic (alkaline)
