Calculate the hydrogen ion concentration...

Calculate the hydrogen ion concentration in the following biological fluids whose pH are given below:
(a) Human muscle-fluid, 6.83 , (b) Human stomach fluid, 1.2
(c) Human blood, 7.38 , (d) Human saliva, 6.4.

Text Solution

Verified by Experts

` because " " pH =- log_(10) [H_3O^(+) ] `
` therefore " " [H_3O^(+) ]= " antilog"_(10) (-pH) `
`[H_3O^(+) ] ` in human saliva
` " " = " antilog"_(10) (-6.4) `
` " " = 3.98 xx 10^(-7) " mol " L^(-1)`
