What happens to acids and bases during neutralization?

Answer 1

An acid is a proton donor, most often in the form of a hydrogen ion. H+

A base is a proton acceptor, most often in the form of a hydroxy ion. OH-

In neutralization the H+ and the OH- combined to form water, leaving whatever cation and anion were involved in the initial mixture to become the representative solute.

Hydrogen cyanide (acid) plus Sodium hydroxide (base) gives water and Sodium cyanide

HCN + NaOH -> H2O + NaCN

Answer 2

The H3O+(aq) ions in the acid clamor to react with the OH-(aq) ions of the base, forming 2H2O(l). The other components of the acid and base react with each other to form a salt. In the case of NaOH(aq) and HCl(aq), the Cl-(aq) ions and the Na+(aq) ions react to form NaCl(s) (table salt). Other salts can be formed, however, when different acids/bases are reacted.

Answer 3

During neutralization, acids and bases react to form water and a salt. The acid donates a proton (H+) to the base, which accepts the proton to form water. The remaining ions from the acid and base combine to form a salt.

Answer 4

Water and an aqueous salt are often formed.

OR

The acid donates protons to the base to form the products.

Answer 5

a type of salt water is formed (ex. H2O + KCl)

Answer 6

An acid and a base neutralize to form a salt and water

eg. HF + KOH gives H2O + KF

Answer 7

Acids can be neutralised by metal carbonates. In the neutralisation reaction between an acid and a metal carbonate, there are three products. The hydrogen ions (H +) from the acid react with the carbonate ions (CO 3 2- ) to form water and carbon dioxide gas. A salt is also produced.

Answer 8

Neutralisation is the reaction of an acid with a base that results in the pH moving towards 7.

It is a useful process that occurs in everyday life such as in the treatment of acid indigestion and the treating of acidic soil by adding lime.

Neutralisation also moves the pH of an alkali down towards seven.

Several different bases can neutralise acids, and water is always produced as a result of these reactions.

Metal oxides and alkalis are two types of base. Basic substances neutralise acids, resulting in the pH of the acid increasing towards 7, and water being produced. A soluble base dissolves in water to form an alkaline solution

Answer 9

To name the salt, the metal ion from the alkali (or base) replaces the hydrogen ion from the acid - (alkali to front, acid to back).

During neutralisation the H+ ion from the acid joins with the OH- ion from the alkali. This is why water is formed in these reactions.

In the neutralisation reaction between an acid and a metal carbonate, there are three products. The hydrogen ions (H+) from the acid react with the carbonate ions (CO32-) to form water and carbon dioxide gas. A salt is also produced.

The salt is named in the same way as before, taking the metal's name from the carbonate and the ending from the type of acid used.

Carbon dioxide can be tested for using lime water (turns from colourless to chalky white)
