Goals
1. Correctly identify and name inorganic salts based on their chemical formulas.
2. Apply the naming of salts in practical problem-solving situations.
Contextualization
Inorganic salts are part of our everyday lives, from the salt on our tables (NaCl) to those used in medicines and various industrial applications. They play vital roles in numerous chemical reactions, both in our bodies and across different industries. For instance, sodium chloride (NaCl) is critical in the food industry for preservation and flavour enhancement. In medicine, salts like magnesium sulfate serve as laxatives, while sodium carbonate (Na2CO3) is indispensable in the glass-making industry. Knowing how to accurately name these salts is essential for precise communication in science and industry.
Subject Relevance
To Remember!
What are Inorganic Salts?
Inorganic salts are formed when an acid reacts with a base, producing a compound that consists of cations (positively charged ions) and anions (negatively charged ions). These salts appear in various contexts, including everyday table salt (NaCl) and compounds used in pharmaceuticals and industries.
-
Formation: Created from the reaction of an acid and a base.
-
Constituents: Made up of both cations and anions.
-
Where Found: Present in foods, medications, and several industries.
Naming Inorganic Salts
The naming convention for inorganic salts follows specific guidelines based on the ions involved. Usually, the name of the salt reflects the names of the acid and base that resulted in its formation. For instance, NaCl is termed sodium chloride, with 'chloride' coming from hydrochloric acid and 'sodium' deriving from sodium hydroxide.
-
Name Source: Comes from the originating acid and base.
-
Example: NaCl is known as sodium chloride.
-
Naming Rules: Each ion follows particular naming conventions.
The Significance of Inorganic Salts
Inorganic salts are crucial across various realms, including food, healthcare, and industry. They serve as preservatives in food, active components in medicines, and are vital in the production processes of glass, paper, and more, showcasing their multifaceted importance.
-
Food: Act as preservatives and flavour enhancers.
-
Healthcare: Key ingredients in medicinal formulations.
-
Industry: Integral to the production of glass, paper, and others.
Practical Applications
-
In the food sector, sodium chloride (NaCl) is commonly used for preservation and seasoning.
-
In the pharmaceutical world, magnesium sulfate is utilized as a laxative.
-
For glass manufacturing, sodium carbonate (Na2CO3) is a critical component.
Key Terms
-
Inorganic Salts: Compounds resulting from the reaction between an acid and a base.
-
Cations: Positive ions found in salts.
-
Anions: Negative ions found in salts.
-
Sodium Chloride: Commonly known as table salt, it exemplifies an inorganic salt.

Salt Naming Activity
This mini-challenge allows you to consolidate your understanding of the naming convention for inorganic salts through a hands-on collaborative task.
Instructions
-
Form groups of 3 to 4 peers.
-
Each group will be provided with samples of different inorganic salts (these can be cards showing chemical formulas or actual samples).
-
Refer to the list of naming rules provided for guidance.
-
Identify the cations and anions in each sample and accurately name the salt.
-
Create a brief presentation outlining the process your group followed for identification and naming.
-
Share your findings with the class.
