What is the best description for a solution with a hydroxide-ion concentration of 1x10-4 M?
A solution with a hydroxide-ion concentration of 1x10-4 M is considered basic because it has a higher concentration of hydroxide ions (OH-) relative to hydronium ions (H+). This concentration indicates a low pH value and a high alkalinity.
What is the OH 1 in a 0.0001 M solution of HCl?
In a 0.0001 M solution of HCl, the concentration of the hydroxide ion (OH-) would be very small and close to zero because HCl is a strong acid that dissociates almost completely in water to form H+ ions and Cl- ions. Therefore, the concentration of hydroxide ions in this solution would be negligible.
Which pH represents a solution with a 1000 times higher OH- than a solution with pH of 5?
A solution with a pH of 5 has an OH- concentration of 1x10^-9 mol/L. To find a solution with 1000 times higher OH- concentration, we multiply 1x10^-9 by 1000 to get 1x10^-6 mol/L. The pH of this solution with a higher OH- concentration would be 8.
What are the hydrogen ion and hydroxide ion concentration in water What is the pH and pOH of pure water?
In pure water, the hydrogen ion (H+) concentration is 1x10^-7 M and the hydroxide ion (OH-) concentration is also 1x10^-7 M. The pH of pure water is 7 (neutral) and the pOH is also 7.
Express the hydroxide and hydronium ion concentrations in pure water at 25C?
In pure water at 25°C, the hydroxide ion concentration is 1.0 x 10^-7 M and the hydronium ion concentration is also 1.0 x 10^-7 M due to the autoionization of water.

If distilled water has a hydronium ion concentration of 1x10-7M what is the pH of a distilled water?
The pH of distilled water with a hydronium ion concentration of 1x10^-7M is 7. Since the pH scale is based on the concentration of hydronium ions in a solution, a concentration of 1x10^-7M corresponds to a pH of 7, indicating a neutral solution.
Express the hydroxide and hydronium ion concentrations in pure water at 25C?
In pure water at 25°C, the hydroxide ion concentration is 1.0 x 10^-7 M and the hydronium ion concentration is also 1.0 x 10^-7 M due to the autoionization of water.
What is the pH of 7 percent NaOH solution?
How to work it out - Calculate the concentration of the solution in terms of molarity. Calculate the hydrogen ion concentration from the fact that multiplying the hydrogen and hydroxide concentrations (in mols per litre) will always give 1x10-14. Take the -log10 of the hydrogen ion concentration.
What is a slightly acidic soulution?
a solution in which the concentration is just slightly smaller than 1x10 to the -7 so the solution is almost neutral
By what factor does the hydroxide ion concentration change if pH solution changes from 10 to 8?
The hydroxide ion concentration increases by a factor of 100 when the pH of a solution decreases by 2 units. This is because pH is a logarithmic scale, so each unit change represents a 10-fold difference in H+ concentration, which in turn affects the concentration of OH- ions.
What is 0.000001 what is the pH?
if 0.000001 is the hydrogen ion concentration the pH is 6
What is the H3O in a solution of OH- 1x10-12M?
H3O+ concentration in a solution where OH- is at 1x10-12 M can be calculated using the equation Kw = [H3O+][OH-]. Since Kw is 1x10^-14 at 25°C, the [H3O+] would be 1x10^-2 M in this case.
What is the H3O plus concentration in a solution that is 100 times less acidic than one having a pH of 3.22?
The H3O+ concentration in a solution with pH 3.22 = 1x10^-3.22 M or 6.03x10^-4 M.If a solution is 100 times less acidic, then the H3O+ concentration will be 6.03x10^-6 M.Put another way, 100 times less acidic will have a pH of 5.22 and H3O+ = 1x10^-5.22 = 6.03x10^-6M
