molecules in water that release hydrogen ions (H+) are acids, while molecules in water that release hydroxide (OH-) are bases. In water solutions, acids affect water molecules, producing hydronium (H3O+) and bases also affect water molecules, producing hydroxide (OH-) ions.

How can water act as a acid or a base?

Water is a base. But, let's say you put lemons in the water, it would now be an acid.


If water can act as an acid or base what is it?

Water is both an acid and a base in the sense that it donates protons to a base thus becoming hydroxide and accepts protons from an acid thus making it hydronium.


Is H2O amphiprotic?

it means that water can act as a base or an acid.


Is limestone a base?

Yes, limestone or calcium carbonate is a base when it is dissolved in water. Water itself can act as either an acid or a base.


What happens when hydrochloric acid and water are together?

The simplest way to answer this is to say that water can act as an acid or a base - giving up a proton (H+) or taking one. When put with an acid, it acts as a base and therefore accepts the proton from the acid. acid + base <---> acid + base HCl + H2O <---> Cl- + H3O+


Can an amphoteric compound act like an acid and a base?

Am amphoteric substance can react as a base but also as an acid.


Does water act as an acid or base with Ammonia?

Water always acts as an acid with Ammonia ,water donates H+ ions forming the Ammonium ion NH4+.


Is water both acidic and basic?

Pure water is neutral, that is, neither acidic nor basic. HOWEVER, it can act as acid as well as base on treating with base and acid respectively. this is said to be aMphoteric chracter of water.


How can a base act like water?

Because water is amphoteric and acts like a Bronsted-Lowry base when mixed with an acid, it will gain a proton and produce hydronium. This is just as a base gains a proton and forms a conjugate acid.


What is formed when an acid and a base is mixed?

when an acid and a base combine, salt and water are formed. This process of reaction of an acid and base is called neutralisation.


Explains water's role in acid-base reactions?

water is responsible for ionization of acid and base, without water the terms acid and base are meaningless.


How does acid behave chemically?

Water is amphoteric. It can act as a weak base or a weak acid. When it is acting as a weak acid, it donates a proton. For instance, it acts as such with ammonia: NH3 + H2O --> NH4+ + OH-
