What is the molarity of OH- in an aqueous solution that is 0.34 M HNO3?

Since HNO3 is a strong acid that completely dissociates in solution, the concentration of H+ ions is equal to the concentration of the acid, which is 0.34 M. The concentration of OH- ions in water is 1.0 x 10^-14 M, therefore, the molarity of OH- ions in the solution is also 1.0 x 10^-14 M.


What is the OH- in a solution with a pOH of 4.22?

The concentration of OH- ions in a solution with a pOH of 4.22 is 5.24 x 10^-5 M.


What is the OH in a solution with a pOH of 4.22?

[OH-] = 1x10^-4.22 or more conventionally, [OH-] = 6.03x10^-5 M


What would be the pH of a solution with a hydroxide ion OH- concentration of 10-12 M?

The pH of a solution can be calculated using the formula: pH = -log[OH-]. Therefore, for a solution with [OH-] concentration of 10-12 M, the pH would be 12.


What is the OH- of a 4.0 x 10-4 M solution of CaOH2?

The hydroxide ion concentration in a 4.0 x 10^-4 M solution of Ca(OH)2 can be calculated by first finding the molarity of OH- ions from Ca(OH)2, which is twice the molarity of the overall solution. Therefore, the [OH-] is 8.0 x 10^-4 M.


What is the pH of a 0.0110 M solution of Ba OH2?

The pH of a 0.0110 M solution of Ba(OH)2 can be calculated by finding the hydroxide ion concentration, which is double the concentration of the Ba(OH)2 solution. Therefore, [OH-] = 2 * 0.0110 M = 0.0220 M. From this, you can calculate the pOH using the formula -log[OH-], and then convert pOH to pH using the relation pH + pOH = 14.


What is the OH of a 4.0 x 10 4 M solution of CaOH2?

The OH concentration in a 4.0 x 10^4 M solution of Ca(OH)2 can be determined by dividing the concentration of Ca(OH)2 by its stoichiometric coefficient, which is 2. Thus, the OH concentration is 2.0 x 10^4 M.


What is the pH of a solution if OH equals 2.3 x 10-5 M?

The pH of a solution can be calculated using the formula pH = 14 - (-log[OH-]). Using the given concentration of 2.3 x 10^-5 M for OH-, the pH would be approximately 9.64.


What is the pH of a solution prepared by mixing 100.00 ml of 0.020 m caoh2 with 50.00 ml of 0.100 m naoh assume that the volumes are additive?

To find the pH of the solution, first calculate the moles of OH- from each solution (Ca(OH)2 and NaOH). Then, add the moles of OH- together and calculate the total volume of the combined solutions. Finally, use the concentration of OH- ions in the combined solution to calculate the pOH and pH of the solution.


What is the OH concentration of a 1 M HCL solution?

The OH concentration of a 1 M HCl solution is very low because HCl is a strong acid that fully dissociates in water to form H+ ions and Cl- ions. Since it is a strong acid, there is no significant amount of OH- ions present in the solution.


What is the OH- in an oven-cleaning solution if the pH is 12.35?

In an oven-cleaning solution with a pH of 12.35, the concentration of hydroxide ions (OH-) would be 1.58 x 10^-1 M. This is calculated by taking the negative logarithm of the hydroxide ion concentration in the solution.


What is the OH- in an ammonia solution if the pH is 10.20?

The OH- concentration in a solution can be calculated using the formula OH- = 10^(14 - pH). Therefore, for a solution with a pH of 10.20, the OH- concentration would be 10^(-3.8) M, or approximately 1.58 x 10^(-4) M.
