It is not to do with buffers.
If you take pure water at 25°C, it dissociates:
H2O ↔ H+ + OH- ( I use H- instead of H3O+ for simplicity)
You ask about bases:
If you add a base, such as NaOH to the water, you introduce a high concentration of OH- ions to the water.
This causes the dissociation equilibrium of the H2O to move to the left. ( In accordance with Le Chettellier) But the re-association of the H+ and OH - from the water is not complete - there are always some H+ ions dissociated
This is determined by the equation:
[H+] [OH-] = 10^-14
You can see this from the pure water where [H+] and [OH-] are both 1*10^-7M - the equation is satisfied
Now on adding the base, the [OH-] increases to 5*10^-3M , What is [H+] in this solution:
[H+] = 10^-14 / (5*10^-3) = 2*10^-12M
There will be a reducing concentration of H+ as [OH-] increases, but always some H+ present
The converse happens with an acid solution
You add acid, say HCl to the water so that [H+] = 5.10^-3
[OH-] = (10^-14)/ (5*10^-3) = 2*10^-2M
Even in the acid solution there will be some OH- ions present.

What happens to the ions bound together as a solid when the solution volume is reduce?
When the volume of a solution containing ions bound together as a solid is reduced, the concentration of the ions in the solution increases. If the solution becomes supersaturated, some ions may begin to precipitate out of the solution, forming solid particles. This process can lead to the formation of new solid phases or the growth of existing solid crystals, depending on the specific ions and conditions of the solution.
Is saltwater a basic solution And if not what are some examples of basic solutions?
baking soda, ammonia, and saltwater are three examples of basic solution's, although we are slowly making the sea acidic =[
In a solution a weak acid produces A a mixture of molecules and ions B all ions C all molecules D anions but no hydronium ions?
Answer A is correct: mixture of ions and moleculesH3O+ and B- and remaining part of UNdissociated HBIn which B- is symbolising any anion remaining from a protlysed part of an acid, e.g. HCl -> Cl-
What happens when silver nitrate solution is stored in zinc vessel?
Some of the silver ions from the silver nitrate solution are deposited as metallic silver on the contacted parts of the zinc vessel and are replaced by half as many zinc ions in the solution.
Why do some solutions conduct electricity while others do not?
How well something conducts electricity depends on its charge and how freely the electrons can move in it, for example, electricity will typically ignore humans in order to flow to a metal because metal is a much better conductor due to the fact that electrons in metal are much less bound to their atoms than that of humans.
A solution conducts electric current can you use this property of the solution to determine if it is acid or basic?
Yes, you can use the electrical conductivity of a solution to infer its acidity or basicity. Acidic solutions generally conduct electricity better than pure water, as they contain more ions such as H+ ions. Basic solutions can also conduct electricity to some extent, as they contain ions such as OH-. By measuring the conductivity of the solution, you can make a rough determination of its acidity or basicity.
Do all bases have hydroxide ions?
No, not all bases contain hydroxide ions. Bases are substances that can accept protons (H+ ions) and increase the concentration of hydroxide ions (OH-) in solution. Some bases, like ammonia (NH3) or sodium bicarbonate (NaHCO3), do not contain hydroxide ions but still have basic properties.
Does a base contain hydroxide ion or produce it in a solution?
Some bases, such as sodium and potassium hydroxides, contain hydroxide ions even in solid form. Others, such as ammonia, produce hydroxide in solution but do not contain any such ions when in pure form.
When the acidic solution is added to the basic solution what happens to the pH does it increase decrease or stays the same?
When an acidic solution is added to a basic solution, the pH will decrease. This is because the addition of the acidic solution will neutralize some of the hydroxide ions in the basic solution, resulting in a decrease in pH.
Why Iron chloride acidic while sodium carbonate basic explain?
Iron chloride is acidic because some of the water molecules in its hydration shell deprotonate. Sodium carbonate is basic because its the salt of a weak acid. Thus, some carbonate ions take protons from water, creating basic hydroxide ions.
What are some of the physical characteristics of a basic solution?
A basic solution has basic solution has a higher concentration of hydroxide ions than hydrogen ions. Three properties of basic solutions are: a pH level between 7 and 14, slimy or soapy and caustic.
Why the Arrhenius model of acids and bases does not include ammonia in solution as base?
The Arrhenius model defines bases as substances that release hydroxide ions (OH-) in solution. Ammonia does not contain hydroxide ions but rather acts as a base by accepting a proton (H+) to form ammonium ions (NH4+). Therefore, ammonia is not included in the Arrhenius model of bases.
Use the concept of hydrolysis to explain why aqueous soln of some salts are acidic basic or neutral.?
Hydrolysis occurs when water breaks apart a salt into its constituent ions, leading to an acidic, basic, or neutral solution. If the cation is a weak acid or the anion is a weak base, the solution will be acidic or basic, respectively. If both the cation and anion are strong acids or bases, the solution will be neutral.
What happens to the ions bound together as a solid when the solution volume is reduce?
When the volume of a solution containing ions bound together as a solid is reduced, the concentration of the ions in the solution increases. If the solution becomes supersaturated, some ions may begin to precipitate out of the solution, forming solid particles. This process can lead to the formation of new solid phases or the growth of existing solid crystals, depending on the specific ions and conditions of the solution.
Do Polyatomic ions always contain oxygen?
In most of the cases it is true but SCN- , Transition metals complex ions and some organic poly atomic ions do not contain oxygen.

An aqueous solution is a solution in which some ionic solutes dissolve in water or is it some molecular solutes dissolve in water?
An aqueous solution is a solution where ionic solutes dissolve in water to form ions. Ionic compounds dissociate into their constituent ions when dissolved in water due to water's ability to stabilize and solvate ions.
