The sum of pH plus pOH?
The sum of pH and pOH is always equal to 14 in a neutral solution at 25°C. This is because pH is a measure of the concentration of H+ ions in a solution while pOH is a measure of the concentration of OH- ions. In a neutral solution, the concentration of H+ ions is equal to the concentration of OH- ions, resulting in a sum of 14.
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.
Does the pH of a neutral solution at room temperature equal the pOH of the solution?
yes. because the ph of a neutrasl solution is 7. Meaning, the pOH of the solution is 7 7=7
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 plus equals 4.1 x 10-9 What is the pOH of this solution?

A solution has H plus equals 6.2 x 10-3 What is the pOH of this solution?
7.8
A solution has H 3.2 10 7 What is the pOH of this solution?
7.5
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
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
When the H in a solution is 1.7 109 M what is the pOH?
To find the pOH of a solution when the H concentration is 1.7 x 10^-9 M, you can first calculate the pH using the formula: pH = -log[H+]. Then, you can find the pOH by subtracting the pH from 14, since pH + pOH = 14 in water. So, if the H concentration is 1.7 x 10^-9 M, the pH is 8.77, and the pOH is 14 - 8.77 = 5.23.
What is the pH and pOH of a 0.0067M HON3 solution?
Since HNO3 is a strong acid, it completely dissociates in solution. HNO3 -> H+ + NO3-. Therefore, the concentration of H+ ions is the same as the concentration of the HNO3 solution, 0.0067M. pH = -log[H+] = -log(0.0067) ≈ 2.18. pOH = 14 - pH ≈ 11.82.
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.

yes. because the ph of a neutrasl solution is 7. Meaning, the pOH of the solution is 7 7=7
What is the poH of 0.2 moles of sulphuric acid?
First u need to know the pH of sulfuric acid: ph= -log[h+] =-log[0.4] 0.3979 now u can find out the POH of sulfuric acid ph+poh=14 poh=14-0.3979 poh=13.6
How does the concentration of H plus and OH- ions determine pH?
The concentration of H+ ions in a solution determines its acidity; the higher the concentration of H+ ions, the lower the pH. The concentration of OH- ions in a solution determines its alkalinity; the higher the concentration of OH- ions, the higher the pH. pH is a logarithmic scale that represents the concentration of H+ ions in a solution.
