Acids, Salt and Bases

What are salts in everyday life?

Salts are ionic compounds formed by the neutralization reaction between an acid and a base, commonly found in food like table salt.

What is table salt chemically known as?

Table salt is chemically known as sodium chloride (NaCl).

How are salts classified?

Salts can be classified as acidic, basic, or neutral based on the properties of their constituent acids and bases.

What is an example of an acidic salt?

An example of an acidic salt is ammonium chloride (NH4Cl), formed from a strong acid and a weak base.

What is a neutral salt?

A neutral salt is formed from the neutralization of a strong acid and a strong base, like sodium chloride (NaCl).

What is a basic salt?

A basic salt is one that is derived from the neutralization of a weak acid and a strong base, such as sodium bicarbonate (NaHCO3).

What is an oxide?

An oxide is a chemical compound that contains at least one oxygen atom and one other element.

How are oxides classified?

Oxides can be classified as acidic, basic, amphoteric, or neutral based on their reactions with acids and bases.

What is an example of an acidic oxide?

An example of an acidic oxide is sulfur dioxide (SO2), which reacts with water to form sulfurous acid.

What is a basic oxide?

A basic oxide is an oxide that reacts with acids to form salts and water, such as sodium oxide (Na2O).

What is an example of an amphoteric oxide?

Aluminum oxide (Al2O3) is an example of an amphoteric oxide, reacting with both acids and bases.

What is a neutral oxide?

Neutral oxides do not react with acids or bases, an example is carbon monoxide (CO).

What are acids?

Acids are substances that donate protons or H+ ions in a solution, characterized by a sour taste.

How are acids classified?

Acids can be classified as strong or weak based on their ability to dissociate in solution.

What is a strong acid?

A strong acid is one that completely dissociates in solution, such as hydrochloric acid (HCl).

What is a weak acid?

A weak acid partially dissociates in solution, an example being acetic acid (CH3COOH).

What is a common use of citric acid?

Citric acid is commonly used as a natural preservative and flavoring agent in food.

What is the pH range of acids?

Acids typically have a pH value less than 7.

What is the role of vinegar in food preparation?

Vinegar, containing acetic acid, is used for flavoring, preserving foods, and in marinades.

What is sodium bicarbonate commonly used for?

Sodium bicarbonate, or baking soda, is often used as a leavening agent in baking.

What is a salt bridge in electrochemical cells?

A salt bridge is a device that connects two half-cells in an electrochemical cell to maintain electrical neutrality.

What is an example of a household cleaning product containing acid?

Many household cleaners use citric acid or acetic acid as effective ingredients for removing limescale.

What is the purpose of oxalic acid in cleaning products?

Oxalic acid is used in cleaning products for its ability to remove rust and stains.

How are hydroxides related to acids and bases?

Hydroxides are bases that can neutralize acids to form salts and water.

What is the chemical formula for sulfuric acid?

The chemical formula for sulfuric acid is H2SO4.

What is the significance of acids and bases in chemistry?

Acids and bases play critical roles in chemical reactions, influencing reaction rates and outcomes.

What is the common name for sodium hydroxide?

Sodium hydroxide is commonly known as lye or caustic soda.
