Question 1:

What type of reaction occurs when an acid and a base react to form a salt and water?

Explanation: When an acid and a base react, they undergo a neutralization reaction, resulting in the formation of a salt and water.

Question 2:

Which of the following indicators is commonly used in acid-base titrations?

Explanation: Phenolphthalein is commonly used as an indicator in acid-base titrations to determine the endpoint of the reaction.

Question 3:

Which of the following is NOT a product of a neutralization reaction?

Explanation: In a neutralization reaction, acid and base react to form salt and water. No gas or acid is produced as a product.

Question 4:

What is the purpose of an acid-base titration?

Explanation: The purpose of an acid-base titration is to determine the concentration of an acid solution by reacting it with a base of known concentration.

Question 5:

What is the stoichiometric point in an acid-base titration?

Explanation: The stoichiometric point in an acid-base titration is the point at which all acid has reacted with the base, and their molar ratios match according to the balanced chemical equation.
