Which of these solutions are acidic a solution with OH equals 2.5 10-9 H plus equals 1.2 10 -4 H plus equals 3.4 10-8 pH equals 4.5 OH equals 1.0 10-4?
solution with [OH-] = 2.5 x 10-9 , A solution with [H+] = 1.2 x 10-4, A solution with pH = 4.5
What is the pH of a solution with a H plus equals 10 -8?
2
What is the pH of a solution with H plus equals 2.3 10-12?
- log(2.3 X 10 -12 ) = 11.6 pH -----------------very little H + concentration in this solution.
What is the pH of a solution with an H plus equals 1.2 x 10-5?
-log(1.2 X 10^-5 M H(+)) = 4.9 pH H(+)
Solve this equation -9h - 6 plus 12h plus 40 equals 22?
The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
What is the H plus in a solution with pOH of 0.253?
1.79x10^-14 M
A solution has H plus equals 4.1 x 10-9 What is the pOH of this solution?
5.6
A solution has H plus equals 6.2 x 10-3 What is the pOH of this solution?
7.8
When the H in a solution is 1.7 109 M what is the pOH?
The pOH is 5,23.
A solution has H 3.2 10 7 What is the pOH of this solution?
7.5
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
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
If the H plus is 0.0020 M the concentration of OH- is?
pH= -log[H+] pH + pOH = 14 pOH = 14 - pH pOH= -log[OH], so the antilog of -pOH will give you the OH concentration.
How does the concentration of H plus and OH- ions determine pH?
pH = - log([H+]) , pOH = - log([OH-] , pH + pOH = 14 [X] = concentration of X
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.
PH is a measure of?
pH and pOH are both logarithmic scales measuring the acidity (or basicness) of a solution. pH is based on the amount of H+ (hydrogen ions), and pOH is based on the amount of OH- (hydroxide ions) in the solution. You can calculate pH if you know the H+ activity: pH = - log10 (H+) pOH is calculated the same way, except with OH- instead of the H+ ions. pOH is also equal to 14 - pH. This is because the pH and pOH scales go from 0 to 14. A solution that is very acidic will have a low pH number and a high pOH number. Conversely, a very basic solution will have a low pOH and a high pH. Water is a neutral solution and has a pH and pOH of 7, which is in the middle.
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
