What is the H plus in a solution with pOH of 0.253?
1.79x10^-14 M
If a solution had a pOH equals 10.7 what would be the H plus?
If an aqueous solution has a pOH value of 10.7 and is at standard temperature and pressure, the pH value is 14 - 10.7 = 3.3. From the definition of pH, this means that the logarithm (to base 10) of the molar concentration of H+, [H+] is -3.3. This can be written as +0.7 - 4. The antilog of 0.7 is 5, to the justified number of significant digits. Therefore, [H+] = 5 X 10-4.
What is the sum of pH and pOH in any solution?
ONLY in pure water at 25 0C :pH + pOH = 14.00
What is a measure of the H plus concentration in a solution?
pH is defined as -log[H+]. This means that if one knows the concentration of hydrogen ion in solution, the pH is simply the negative logarithm (base 10) of that. Similarly, one can find the pOH simply by substituting the concentration of OH- for the concentration of H+ in the aforementioned formula.
How can th pH of a solution be calculated if the pOH is known?
We can subtract pOH from 14, using the formula pH + pOH = 14. This is only true at 14 degrees Celsius.
A solution has H 3.2 10 7 What is the pOH of this solution?
7.5
A solution has H plus equals 4.1 x 10-9 What is the pOH of this solution?
5.6
A solution of HCl has H 2.5 x 10-5 What is the pOH of this solution?
pH + pOH = 14 If the pH is 3.4, the pOH is 10.6
When the H in a solution is 1.7 109 M what is the pOH?
The pOH is 5,23.
A solution has H plus equals 6.2 x 10-3 What is the pOH of this solution?
7.8
What is the H ion concentration in a 4.8x10-2 M KOH solution?
pOH = -log(10)[OH^-] pOH = -log(10) [ 48. x 10^-2] pOH = - (-1.31875...) pOH = 1.31875... pH = 14 - pOH pH = 14 - 1.31875... pH = 12.68124... pH = 12.68
What is the solution's pH and pOH?
pH and pOH are a measure of the concentration of the hydronium ions and hydroxyl ions respectively in the solution. pH = -log[H+] pOH = -log[OH-] and they are related: pH + pOH = 14
Calculate the OH- of a solution that has a pH of 2.40?
The pOH is the negative log of the OH- concentration. Thus, pOH = -log 2.0x10^-2pOH = 1.699 = 1.7
What is the H plus in a solution with pOH of 0.253?
1.79x10^-14 M
A solution of HBr has H 2.1 x 10-6 What is the pH of this solution?
By definition pH = -log[H+], so pH = -log(4.9*10-4) = 3.31Only at 25oC: pOH = 14.00 - pH, so 14.00 - 3.31 = 10.69 = pOH
What solutions are acidic Assume all solutions are at 25C Kw equals 1.0 x 10-14 at 25C?
A solution with [H+] = 1.1 x 10-7 A solution with pOH = 10.1
If a solution had a pOH equals 10.7 what would be the H plus?
If an aqueous solution has a pOH value of 10.7 and is at standard temperature and pressure, the pH value is 14 - 10.7 = 3.3. From the definition of pH, this means that the logarithm (to base 10) of the molar concentration of H+, [H+] is -3.3. This can be written as +0.7 - 4. The antilog of 0.7 is 5, to the justified number of significant digits. Therefore, [H+] = 5 X 10-4.
