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

What is the concentration of the hydroxide ion given that the concentration of the hydronium ion is 1.5x10-5M?

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.


What is hydroxide ion concentration if pH 8?

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)


What is the hydroxide ion concentration of a solution that has a pH of 8.57?

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.


Which out of hydrchloric acid or sodium hydroxide has a higher pH?

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.


How are acids and bases different how do their pH valies differ?

the lower the pH the higher the hydrogen so acid 1-6 is higher in hydrogen compared to base 8-14. 7 is neutral

What is the hydroxide ion if the pH is 5?

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.


Which solutions has a greater concentration of hydroxide ions a solution of pH 3 or a solution of pH 9?

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.


How many more hydroxide ions are there in a solution with a pH of 9 than in 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.

Calculate concentration of hydroxide ion with given pH?

Ist step, calculate pOH value by using formula pH + pOH = 14 2nd step, pOH = -log[OH], [OH] = - Antilog of pOH


Is 9 the pH of equal numbers of hydronium ions and hydroxide ions?

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.

How many times more hydroxide ions are there in a solution with a pH of 9 than a solution with a pH of 3?

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.


How many times more hydroxide ions are there in a solution with a pH of a 9 than in a solution with a pH of 3?

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.


What is the hydronium ion concentration when pH is 8.2?

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.


Does a pH of 3 have a greater hydrogen ion concentration than a 9 pH?

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.)
