The pH of a 4.5*10-7 M OH- solution is 7.7
[H3O+] = 1x10^-7 M = hydronium ion concentration[OH-] = 1x10^-7 M = hydroxide ion concnetration
A solution with a hydroxide ion concentration of 1x10^-4 M would be considered basic. This concentration indicates a low concentration of hydroxide ions, suggesting a slightly basic pH.
In pure water, the hydrogen ion (H+) concentration is 1x10^-7 M and the hydroxide ion (OH-) concentration is also 1x10^-7 M. The pH of pure water is 7 (neutral) and the pOH is also 7.
The hydroxide ion concentration can be calculated using the formula [OH-] = 10^-(14-pH). Thus, for a solution with pH 12.40, the hydroxide ion concentration would be 10^-(14-12.40), which is equal to 2.51 x 10^-2 M.
A solution with a hydroxide-ion concentration of 1x10-4 M is considered basic because it has a higher concentration of hydroxide ions (OH-) relative to hydronium ions (H+). This concentration indicates a low pH value and a high alkalinity.
[H3O+] = 1x10^-7 M = hydronium ion concentration[OH-] = 1x10^-7 M = hydroxide ion concnetration
The concentration of the hydroxide ion can be determined using the ion product constant for water (Kw). Since water autoionizes to form equal concentrations of hydronium and hydroxide ions, if the hydronium ion concentration is 1.5x10-5 M, then the hydroxide ion concentration would also be 1.5x10-5 M.
A solution with a hydroxide ion concentration of 1x10^-4 M would be considered basic. This concentration indicates a low concentration of hydroxide ions, suggesting a slightly basic pH.
In pure water, the hydrogen ion (H+) concentration is 1x10^-7 M and the hydroxide ion (OH-) concentration is also 1x10^-7 M. The pH of pure water is 7 (neutral) and the pOH is also 7.
By using the auto-ionization constant of water (Kw = 1.0 x 10^-14), you can find the hydronium ion concentration by dividing Kw by the given hydroxide ion concentration. The hydronium ion concentration would be 4.00 x 10^-11 M in this case.
-log(0.13) = 0.88 ----------- 14 - 0.88 = 13.12 1/10(13.12) = 7.59 X 10-14 M hydroxide ion concentration ----------------------------------------------------------
The hydroxide ion concentration can be calculated using the formula [OH-] = 10^-(14-pH). Thus, for a solution with pH 12.40, the hydroxide ion concentration would be 10^-(14-12.40), which is equal to 2.51 x 10^-2 M.
A solution with a hydroxide-ion concentration of 1x10-4 M is considered basic because it has a higher concentration of hydroxide ions (OH-) relative to hydronium ions (H+). This concentration indicates a low pH value and a high alkalinity.
In a solution of pH of 2, there is more hydrogen ions then hydroxide ions because hydroxide ions only form with a pH pf 7 or more.Note: There are comments associated with this question. See the Discuss:What_can_you_say_about_the_amount_of_hydrogen_ions_relative_to_the_amount_of_hydrogen_ions_in_a_solution_that_has_a_pH_of_2to add to the conversation.
The highest pH on the scale is 14. But pH over 14 is also possible: for example a sample of 1o M sodium hydroxide solution has a pH of 15.
The pH of a solution with a hydroxide ion concentration of 0.0002 M would be 10.3. This is because pH is calculated as the negative logarithm of the hydrogen ion concentration in a solution, and in this case, the pOH would be 3.7 (14 - 10.3).
pH= -log[H+] where [H+] denotes the conc. of H+ ion. => 9= -log[H+] =>-9= log[H+] =>10-9= [H+] [OH-]= 10-14/10-9 = 10-5
