Answer 1

The given question is incomplete. The complete question is:

An acidic solution at 25°C will have a hydronium ion concentration ________ and a pH value ________.

`[H_3O^+]` >
`1* 10^(-7)` M, pH < 7.00

`[H_3O^+]` <
`1* 10^(-7)`, pH < 7.00

`[H_3O^+]` <
`1* 10^(-7)`,, pH > 7.00

`[H_3O^+]` >
`1* 10^(-7)`,, pH > 7.00

Answer:
`[H_3O^+]` >
`1* 10^(-7)` M, pH < 7.00

Step-by-step explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

`pH=-\log [H_3O^+]`

`7=-log[H_3O^+]`

`[H_3O^+]=10^(-7)`

As pH of acids is less than 7, the hydronium ion concentration is greater than

Thus the correct option is
`[H_3O^+]` >
`1* 10^(-7)` M, pH < 7.00
