Question

18. A solution in which [H+] = 10-8 M has a pH of ___ and is ___. *

2 points

(a) 8, acidic

(b) 6, basic

(c) 8, basic

(d) None

​

Answer 1

Answer:

We know that pH=−log[H

+

]

pH=8

Thus, 8=−log[H

+

]

Hence [H

+

]=10

−8

Thus, concentration of H

+

is 10

−8

M

Answer 2

The correct answer is option c.

pH can be calculated as ,

pH = - log₁₀[H+]

      = - log₁₀[10⁻⁸]

      = 8 log₁₀10

      =8

The pH greater than 7 i.e 8 indicates that it is a basic solution.
