Elements react with acids to produce salts. For example, Sodium metal reacts with Hydrocloric acid and produces sodium chloride or common salt.
Thus, sodium reacts with acids, but the resulting salts react differently. If you imagine parents as elements and children as the salts and don't you see they react differently!
The statement "the properties of salts are different from the properties of the elements" means that when elements combine to form salts, the resulting compound (the salt) has different characteristics compared to the individual elements that make it up.
To understand this statement better, let's break it down:
1. Elements: Elements are pure substances that cannot be broken down into simpler substances. They are composed of only one type of atom. Each element has its own unique set of physical and chemical properties. For example, sodium (Na) is a soft, shiny metal that reacts violently with water, while chlorine (Cl) is a greenish-yellow gas with a strong smell.
2. Salts: Salts are compounds that form when elements combine through a chemical reaction called ionization. In this process, one element (the metal) donates its outermost electron(s) to another element (the non-metal). This transfer of electrons creates positively and negatively charged ions, which are held together by electrostatic forces to form a crystal lattice structure of the salt. For example, when sodium (Na) and chlorine (Cl) combine, they form sodium chloride (NaCl), which is common table salt.
The properties of salts are different from the properties of the elements involved in their formation due to the following factors:
a. Ionic Bonding: Salts are held together by ionic bonds, which are relatively strong electrostatic attractions between positively and negatively charged ions. These bonds give salts high melting points and tend to make them brittle.
b. Solubility: Many salts dissolve in water and form aqueous solutions with distinct properties, such as the ability to conduct electricity. This is because the dissociated ions in the solution are free to move and carry electric charge.
c. Chemical Reactivity: Salts can undergo various chemical reactions, often different from those of their constituent elements. For example, sodium chloride (NaCl) does not react explosively with water like pure sodium metal does.
In summary, the statement means that the properties of salts, such as their melting points, solubility, and reactivity, are different from the properties of the individual elements that form them.
