Question

write three properties of salt. Give Example of two salts​

Answer 1

Answer:

$\huge\underline{\textbf{AnswEr}}$

$\underline\bold{salt:-}$

salt are the ionic compound which are produced after the neutralization reaction between acid and base, salts are electrically neutral.there are number of salt but sodium chloride is the most common among them.

$\underline\bold{characteristics \ of \ salt:-}$

• most of the salts are crystalline solid.
• salt may be transparent or opaque.
• most of the salts are soluble in water.
• solution of the salts conduct electricity in their matter state also.
• neutral salts are odourless.
• salt can be colourless or coloured.

$\underline\bold{family \ of \ salt:-}$

salt having common acidic or basic radicals are said to to belong to the same family.

example:

sodium chloride and potassium chloride belongs to chloride family

$\underline\bold{sodium \ chloride:-}$

it is formed after the reaction between sodium hydroxide (a strong base) and hydrochloric acid ( a strong acid).

$\underline\bold{potassium \ chloride :-}$

it is formed after the reaction between potassium hydroxide (a strong base) and hydrochloric acid (a strong acid) .

Answer 2

Properties of Salt

• Salt is made up of Sodium and Chlorine.
• Salt has negatively charged ions (OH-) and positively charged ions (H+).
• Due to their oppositely charged ions, the ions are attracted towards each other with an electrostatic force of attraction which is called an ionic bond.
• An equal number of opposite charges makes the ionic compounds neutral with no charge.
• Salt water is a good conductor of electricity.
• Salts are ionic in nature due to the presence of ions.

1. They are brittle, hard and crystalline solids.

• Salt is white, odorless and it has a salty taste.
• All potassium (K), ammonium (NH4+) and sodium (Na) salts are soluble in water (H2O).
• Nitrites, nitrates, and bicarbonates can be dissolved in water.
• All metallic oxides, metallic carbonates, hydroxides, phosphates, and sulphides are insoluble in water.

Types of Salts

Normal salt

Normal salts are electrically neutral. They are formed when acids and bases neutralize, and these salts don’t have replaceable hydrogen or hydroxyl in their formula. Metallic ions replace the hydrogen ions completely. For e.g. NaCl, KNO3, CuSO4 etc.

Basic salt

Salt formed due to partial replacement of hydroxy radicals of a diacidic base or a triacidic base with an acid radical. This kind of acid consists of hydroxyl, metallic cation and anion of an acid. For e.g. basic Zinc chloride, basic magnesium chloride, ZnOHCL etc.

Acidic salt

If a polybasic acid is neutralized partly by a base, the salt formed is acidic. In other words, such salt is produced by the replacement of only a part of the acidic hydrogen of the polybasic acid by a metal. For e.g. NaHSO4, NaHS, NaHCO3 etc.
