Introduction

This work discusses an ionic compound (element description, analyzes both anion and cation, designating the positive and negative ion, and showing the various applications. The assignment also outlines the chemical reactions in terms of combination, combustion, replacement, and decomposition. The ionic compound selected for this work is sodium chloride.

Chemistry encompasses the interactions within the environment a person lives. Examples include air people breathe, food, and product creation. The alterations experienced in chemistry like changes from solid to liquid, and then gaseous state leads to the formation of new products. These chemical changes processes are irreversible while the physical alterations are reversible. As such, chemical changes cause a color change, precipitate production, temperature changes, and bubbles production.

Sodium chloride

The ionic compound between Na+ and Cl− is characterized by single charges for both the positive and negative charges. Only one ion is required to balance the overall charge of this ionic compound. The ionic formula of sodium chloride is derived from the first cation and anion charges. Na+ and Cl− provide NaCl for the compound found in Na+ and Cl−, thus the ionic formula is NaCl. Sodium chloride. This formula generates a Na2Cl2 balanced charge, however, its convention relies on the ions lowest ratio. Also, NaCl is has a combination name of the anion (chloride) and cation (sodium). Humans depend on the sodium element from the ionic compound (NaCl).

Sodium chloride is considered an ionic compound because it comprises cube-shaped crystals with sodium and chlorine elements. The diagram of sodium chloride has the sodium ion bonded using six chloride ions, and the chloride ion also bonded to six sodium ions. Thus, the ratio of sodium to chloride ions in the ionic compound becomes 1:1, making the empirical formula formed be NaCl, this because 1 chlorine molecule (Cl2) reacts with two sodium atoms to create 2Na+ and 2Cl– ions to a ratio of 1:1. However, according to (TOPIC3.IONICCOMPOUNDS ), when the formula is written, a simple whole-number ratio is applied for the anion and cation.

The reaction of Sodium chloride with sulfuric acid

The reaction of sodium chloride with sulfuric acid is a chemical reaction that forms sodium hydrogen sulfate and hydrogen chloride.

Chemical equation

2NaCl + H2SO4 →Na2SO4 +2HCl

Combination and decomposition chemical reactions

Decomposition reaction begins with one substance and generates more than one element, which is means it decomposes (Jessie, 2020). Decomposition is characterized by a single reactant substance but more than one element as the products. An example of decomposition is the sodium hydrogen carbonate illustrated below.

2 NaHCO3(s) → Na2CO3(s) + + H2O (l) + CO2 (g)

From the single substance sodium hydrogen carbonate, three substances namely sodium carbonate, water, and carbon dioxide are produced.

Combination reaction

This reaction is also called composition reaction. It creates a single element from various reactants. It is characterized by one substance as the product (Jessie, 2020). Sometimes there are coefficient existence apart from the one element, however, when a chemical reaction occurs and a single product is generated then it is deemed as a combination reaction. An example of the reaction is displayed below for oxygen and hydrogen gas.

2 H2(g) + O2(g) → 2 H2O(l)

The resultant product from the reaction of both gases (oxygen and hydrogen) produced water (). Despite the formation of two water molecules, only one substance is created as the final product, thus a combination reaction.

Application of sodium chloride

Sodium chloride helps balance the electrolyte levels of fluids within an individual’s body (ChemicalSafetyFacts, 2020). When the levels are low or high, a person can experience either hydration or dehydration.

Intravenous sodium chloride is used in hospitals for water and salt supply purposes to the sick to minimize dehydration (ChemicalSafetyFacts, 2020). The roadways and path walks are usually de-iced using sodium chloride.

Thirdly, sodium chloride has been used to preserve and flavor foods for many years past (ChemicalSafetyFacts, 2020).it helps ferment foods like kefir and pickle. The preservative salt prevents food spoilage keeping foods like meat and fish fresh.

 

 

4 a) Iron rust in the presence of air and moisture or water (Zaki, 2006). When dipped in the test tube with water, oil, and air there was no rust since the oil layer absorbed the air. In the third case, anhydrous calcium chloride, and dry air, the iron did not rust as well because the anhydrous calcium chloride is a drying agent, thus absorbing the moisture in the iron.

1. b) Rusting is a chemical reaction considered as an oxidation reaction. In this circumstance, the iron reacts with oxygen and water to produce iron (III) oxide that is the rust.

Iron + Oxygen + Water → Hydrated iron (III) oxide. For rusting to occur, there must be oxygen, moisture, or water.

1. c) Rust formation requires iron, oxygen, and water; the process is expressed below using a chemical equation and formula.

3O2 + 6H2O → 4Fe (OH) 3. (Chris, 2018)

Conclusion

Ionic compounds are derived from the ionic charge, which an element’s atom shows and it originates from the group where an element belongs. Sodium chloride the element under study is a group one element meaning it has 1 electron and proton for the chlorine and sodium, respectively. The sodium takes the cation+1 charge while the chloride contains the anion part (-). The second area of the assignment involved reacting sodium chloride (an ionic compound with a sulfuric acid molecule) to tests the chemical reactions and products released. Thirdly, combination, and decomposition reactions were compared and contrasted. Finally, chemical changes example was analyzed, where rusting was picked as the case study, and an energy diagram created from the reactants and products generated.
