What is the best description for a solution with a hydroxide-ion concentration of 1x10-4 M?
Assuming that by M you mean moles per liter, you have described a solution with a pH of 10, which is strongly alkaline.
Express the hydroxide and hydronium ion concentrations in pure water at 25C?
[H3O+] = 1x10^-7 M = hydronium ion concentration[OH-] = 1x10^-7 M = hydroxide ion concnetration
What is the OH 1 in a 0.0001 M solution of HCl?
From the equilibrium of water dissociation, kW is equal to the product of hydrogen ions and hydroxyl ions. The hydrogen ion concentration is 1x10^(-4). Hence, at 298 K, the hydroxyl ion concentration would be 1x10^(-10).
By what factor does the hydroxide ion concentration change if pH solution changes from 10 to 8?
pH 10 means [H+] = 1x10^(-10) mol dm-3 (0.0000000001 mol dm-3) pH 8 means [H+] = 1x10^(-8) mol dm-3 (0.00000001 mol dm-3) So basically it's changed by a factor of 100.
If a solution has a pH of 9the solution is?
A solution with a pH of 9 is a weak alkaline. A pH of 9 is a weak base. The concentration of H+ ions contributes to the pH of a substance. As the pH number goes up, the concentration of H+ ions goes down. It directly translates to pHx= 1x10 to the power of -x moles per liter.

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
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
What ions does a neutral solution contain and what is the quantity of each?
A neutral solution can contain ions of hydrogen, hydroxide, and the cation and anion of any neutral salt. There are equal numbers of hydrogen and hydroxide ions, and also an equal (but usually different) number of the other pair of ions.

From the equilibrium of water dissociation, kW is equal to the product of hydrogen ions and hydroxyl ions. The hydrogen ion concentration is 1x10^(-4). Hence, at 298 K, the hydroxyl ion concentration would be 1x10^(-10).

pH 10 means [H+] = 1x10^(-10) mol dm-3 (0.0000000001 mol dm-3) pH 8 means [H+] = 1x10^(-8) mol dm-3 (0.00000001 mol dm-3) So basically it's changed by a factor of 100.

Given that you have a H3O concentration of 0.0034 M what is the OH-?
[H3O+][OH-] = Kw = 1x10^-14[OH-] = 1x10^-14/0.0034 = 1x10^-14/3.4x10^-3[OH-] = 2.9x10^-12 M
What is the molarity of a strong acid solution with a pH of 2?
1x10-2M
Name the products of the dissociation of water and give their concentration in pure water?
2H2O H3O^+1 + OH^-1at 25 deg C, [H3O+] = [OH-] = 1x10^-7 mol/LH3O^+1 = hydronium ionOH^-1 = hydroxide ion
