Neutralization Reaction - acids + BasesRomanian translation by Alexander Ovsov

Introduction and also Definitions:

A salt is any compound which can be obtained from the neutralization of one acid and also a base. The word "neutralization" is used since the acid and base properties of H+ and OH- are ruined or neutralized. In the reaction, H+ and OH- integrate to form HOH or H2O or water molecules. A neutralization is a type of dual replacement reaction. A salt is the product of an acid-base reaction and is a much broader term then common table salt as presented in the an initial reaction.

You are watching: What are the products of a neutralization reaction?

The following are some examples of neutralization reaction to kind salts.

a. HCl + NaOH --> NaCl + HOH

b. H2SO4 + 2 NH4OH --> (NH4)2SO4 + 2 HOH

c. 2 NaOH + H2CO3 --> N2CO3 + 2 NaOH see the graphics on the left. Carbon dioxide in the breath reacts very first with the water to kind carbonic acid:

CO2 + H2O --> H2CO3

The carbonic acid then additional reacts v the lime water in the neutralization reaction. The phenolphthalein is pink in the existence of base and turns colorless when every one of the base has actually been neutralized and there is a slight excess that the carbonic acid.

d. Lime water: Ca(OH)2 + H2CO3 --> CaCO3 + 2 HOH


HNO3 + KOH -->

Answer KNO3 + Answer HOH
H3PO4 + 3 NaOH --> Answer Na3PO4 + Answer 3 HOH

The non-metal oxide gases react with water to develop acids (ammonia to produce a base).

Example: SO2 + HOH === H2SO3 2 NO2 + HOH === HNO2 + HNO3 Cl2 + HOH === HClO + HCl

SO3 + HOH-->

Answer H2SO4
NH3 + HOH --> Answer NH4OH

In the house the corrosive gases are developed by smoking, aerosol oven cleaners, disinfectant sprays, window cleaners, etc. The improper mix of a toilet key cleaner (HCl) or any kind of acid through a chlorine-type bleach may produce fatal results from the generation that chlorine gas. The enhancement of ammonia to bleach likewise produces a poisonous gas, chloroamine.

Health results of Acids and also Bases:

Acids and bases are examples of corrosive prisoner which react in your ar on organization cells. Chemistry that space very an easy or very acidic are reactive. These chemicals can cause severe burns. Car battery acid is one acidic chemical the is reactive. Car batteries save on computer a stronger type of several of the same acid the is in mountain rain. Household drain cleaners regularly contain lye, a really alkaline chemical that is reactive.

Acids and bases are capable of causing severe "burns" similar to burns developed by heat. These materials act by very first dehydrating to move structures. Climate proteins frameworks are ruined by the action of mountain or basic which catalyzes the separating of peptide bonds. Smaller and also smaller pieces result, bring about the ultimate fragmentation of the tissue.

The eyes and lungs are an especially sensitive to corrosive poisons. The cornea of the eye is damaged by acid or basic burns. Pulmonary edema (filling with water) occurs once highly focused corrosive pollutants (acute poisoning) with the lungs. The lining that the nose, sinuses and also lungs end up being irritated and also water logged (by dehydration that cells). This occurs in an attempt to dilute the toxicity agent. This waterlogged condition stays clear of the regular exchange of oxygen and carbon dioxide. The victim may die of immediate suffocation, a secondary attack that bacteria leading to pneumonia, or suffer irreversible lung damage. Lengthy term subchronic acid-base dosage effects are much less well understood.

Air pollutants such as sulfur oxides, nitrogen oxides, chlorine, and also ammonia all have corrosive results on the respiratory tract tract. The solubility of the gases in water determines their fate. The most soluble gases, such together ammonia and also sulfur oxides, space promptly adsorbed to the moist surfaces of the upper airways resulting in nasal and also throat irritation. Less soluble gases, such together nitrogen oxides and also chlorine, create their impacts in the depths of the lungs causing pulmonary edema, pneumonia, and also emphysema (loss the elasticity and surface area).


The above graphic demonstrates the following reactions. The phenolphthalein is pink in the existence of a base and colorless after the citric mountain neutralizes the base.

A bottle of drain cleaner includes lye (NaOH). First-Aid treatment is to provide citrus juice (citric acid) or vinegar (acetic acid). Write reactions.

H3C6H8O6 + NaOH --> Answer Na3(C6H8O6) + Answer 3 HOH
HC2H3O2 + NaOH --> Answer Na(C2H3O2) + Answer 3 HOH

First-Aid therapies Use Neutralization:

The interpretation of "Danger" and also First-Aid labels on household cleaners provides an practice in the use of acid-base principles.


A toilet bowl cleaner - Danger: Corrosive - produces chemical burns. Consists of Hydrochloric Acid. Do not acquire in eyes, on skin. Might be fatal if swallowed. Do not breath vapor or fumes. First-Aid: internal - contact physician. Drink a teaspoon of magnesia, chalk, tiny pieces of soap, life egg white, or milk. External - eye - Wash through water because that 15 minutes. Skin - Wipe mountain off gently, flood with water, cover v moist magnesia or baking soda.

Solution: The First-Aid is composed of one of two people diluting the acid, coating the stomach lining, or neutralizing it.

Mg(OH)2 + HCl --> MgCl2 + HOH magnesia

The laboratory has red bottles for acid burns i beg your pardon contain baking soda (NaHCO3). Write the neutralization reaction by applying the Bronsted definition.

HCl + NaHCO3 --> NaCl + H2CO3

Bronsted acids or bases, above?
Answer? mountain - offers away hydrogen ion. Answer? basic - accepts hydrogen ion. H2CO3 continues to decompose to do bubbles that CO2.

Stomach Antacids:

Antacids are an alleged to diminish the lot of hydrochloric mountain in the stomach by reacting v excess acid. Castle are supplied in the therapy of gastric hyperacidity and peptic ulcers. Several of the ingredients in antacids are: Magnesia (MgO), milk the magnesia (Mg(OH)2, calcium carbonate (CaCO3), sodium bicarbonate (NaHCO3), dihydroxyaluminum sodium carbonate (NaAl(OH)2CO3), aluminum hydroxide gelatin (Al(OH)3). Several of these will certainly habe height be recognized as Bronsted bases.
