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 ________.
[tex][H_3O^+][/tex] > [tex]1\times 10^{-7}[/tex] M, pH < 7.00
[tex][H_3O^+][/tex] < [tex]1\times 10^{-7}[/tex], pH < 7.00
[tex][H_3O^+][/tex] < [tex]1\times 10^{-7}[/tex],, pH > 7.00
[tex][H_3O^+][/tex] > [tex]1\times 10^{-7}[/tex],, pH > 7.00
Answer: [tex][H_3O^+][/tex] > [tex]1\times 10^{-7}[/tex] M, pH < 7.00
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.
[tex]pH=-\log [H_3O^+][/tex]
[tex]7=-log[H_3O^+][/tex]
[tex][H_3O^+]=10^{-7}[/tex]
As pH of acids is less than 7, the hydronium ion concentration is greater than
Thus the correct option is [tex][H_3O^+][/tex] > [tex]1\times 10^{-7}[/tex] M, pH < 7.00
