The hydrogen ion concentration of a solution is ` 3.98 xx 10 ^( - 6 ) ` mole per liter. The pH value of this solution will be

A

`6.0 `

B

`5.8 `

C

`5.4 `

D

`5.9 `

Text Solution

Verified by Experts

The correct Answer is:
C
`pH = - log [ H^ + ] `
` = - log ( 3.98 xx 10 ^( - 6 ) ) `
` = - log 3.98 - log 10 ^( - 6 ) `
` = -0.59 + 6 = 5.41 `
