(II) Human stomach fluid, 1.2

(III) Human muscle fluid, 6.83

(IV) Human blood, 7.38.

##### Solution :-

(I) Human saliva, 6.4

pH = 6.4

6.4 = – log [H+] [H+

= 3.98 x 10-7

(II) Human stomach fluid, 1.2

pH =1.2

1.2 = – log [H+]

∴[H+] = 0.063

(III) Human muscle fluid 6.83

pH = 6.83

pH = – log [H+]

∴6.83 = – log [H+] [H+

=1.48 x 10-7 M

(IV) Human blood, 7.38

pH = 7.38 = – log [H+]

∴ [H+] = 4.17 x 10-8 M
