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
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.
To find the hydronium ion concentration from pH, set base 10 to the negative power of the pH. Here that corresponds to 10 to the power of -8.75 The answer is 0.000000002 or 2x10^-9 Although this response is correct in saying that concentration and pH are based on sets of base 10; however, it is incorrect in it's response. From pH--> [H30] -log(pH) From [H30]---> pH 10^(-pH)
The hydroxide ion concentration can be calculated using the formula: [OH-] = 10^(-pOH). Given that pH + pOH = 14 in water, we can find that the pOH of the solution is 14 - 8.57 = 5.43. Therefore, [OH-] = 10^(-5.43) = 2.51 x 10^(-6) M.
Sodium hydroxide is a strong base with the chemical formula NaOH. Ammonia water is usually a solution of NH3 and H2O mixed together to form NH4OH,. This is usually the stuff people clean with and is also a strong base. Ammonia (the gas) is just NH3.
the lower the pH the higher the hydrogen so acid 1-6 is higher in hydrogen compared to base 8-14. 7 is neutral
probably protonated so just water, the pKa of hydroxide is around 14.7 and therefore just over 1 out of 10^10 molecules of water is de protonated giving the hydroxide.
A solution with a pH of 9 has a greater concentration of hydroxide ions than a solution with a pH of 3. The pH scale is a logarithmic scale, with each unit representing a tenfold difference in hydrogen ion concentration. Therefore, a solution with a pH of 9 has a concentration of hydroxide ions 1,000 times greater than a solution with a pH of 3.
The concentration of hydroxide ion is realted to pH by the pKw (10-14) At pH 9 the concentration of OH- is 10-5, at pH 3, 10-11. The ratio is 106 so there are a million times as many OH- in pH 9.

Ist step, calculate pOH value by using formula pH + pOH = 14 2nd step, pOH = -log[OH], [OH] = - Antilog of pOH
No. pH is the negative logarithm of the concentration of the hydronium ion. Equal numbers of hydronium ions and hydroxyl ions occurrs only when a solution is neutral.
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.
There are 10^6 (1 million) times more hydroxide ions in a solution with a pH of 9 compared to a pH of 3. This is because each unit increase in pH represents a tenfold decrease in hydrogen ion concentration, resulting in a corresponding increase in hydroxide ions.
The pH scale is logarithmic, so each unit corresponds to a 10-fold difference in hydrogen ion concentration. Therefore, a solution with a pH of 9 has 1,000,000 (10^6) times more hydroxide ions than a solution with a pH of 3.
The hydronium ion concentration can be calculated using the formula [H3O+] = 10^(-pH). Therefore, for a pH of 8.2, the hydronium ion concentration would be 10^(-8.2) = 6.31 x 10^(-9) mol/L.
pH come from "pondus hydrogenii" or "potential hydrogen." It measures the concentration of hydrogen ions. Mathematically, pH = -log[H+] Therefore, to answer your question, a pH of 3 will have a 10-3M of hydrogen ions where as the pH 9 solution will have a 10-9M of hydrogen ions. The lower the pH the higher its H+ concentration and the more acidic it is. (A pH of 9 is actually basic.)
