Family of Salts

The video tutorial explores the nature of solids and various types of salts, including normal, acidic, basic, double, mixed, and complex salts. It explains how salts are formed by replacing hydrogen in acids with metals or ammonium ions. The video also covers the historical use of pigments in European painting, the properties of styptic pencils, and the role of complex salts in preventing caking in table salt. The tutorial provides practical examples and applications of these chemical compounds.

What is a salt formed when the hydrogen of an acid is completely replaced by a metal called?

• Double salt

• Acidic salt

• Normal salt

• Basic salt

Which of the following is an example of a basic salt used historically in painting?

• Lead carbonate hydroxide

• Magnesium chloride

• Sodium chloride

• Potassium nitrate

What is a double salt?

• A salt formed by replacing all hydrogen atoms with metal

• A salt that dissolves in water to form a single ion

• A salt with two different cations or anions

• A salt with only one type of ion

How are mixed salts formed?

• By dissolving a single salt in water

• By crystallizing a solution of two salts in equal proportions

• By crystallizing a solution of two salts in unequal proportions

• By replacing oxide ions with hydroxide ions

What is the role of potassium hexa cyano ferrate in table salt?

• To enhance flavor

• To provide nutritional value

• To act as an anti-caking agent

• To increase solubility

Which ions are not present in the solution of a complex salt like potassium hexa cyano ferrate?

• Potassium ions

• Chloride ions

• Iron and cyanide ions

• Sodium ions

What distinguishes a complex salt from other types of salts?

• It contains only one type of ion

• It is formed by replacing all hydrogen atoms with metal

• It forms new ions in solution

• It is always soluble in water
