Titration of Strong Acid With Strong Base

The video tutorial covers the concept of acid-base titration, focusing on the neutralization reaction to determine the concentration of an unknown reagent. It explains the importance of reaching the equivalence point and the use of indicators like phenolphthalein. The tutorial provides a detailed guide on setting up the titration apparatus, performing a rough titration for estimation, and conducting an accurate titration to calculate the concentration of hydrochloric acid using sodium hydroxide as the titrant.

What is the purpose of an acid-base titration?

• To produce more acid

• To increase the temperature of the solution

• To determine the concentration of an unknown solution

• To change the color of the solution

What is the role of an indicator in a titration?

• To neutralize the acid

• To measure the pH directly

• To show a visible color change at the equivalence point

• To increase the reaction speed

Which equipment is essential for setting up a titration experiment?

• A thermometer and a pipette

• A burette and an Erlenmeyer flask

• A beaker and a test tube

• A balance and a graduated cylinder

How can you ensure accuracy when reading the burette?

• By reading from the top of the meniscus

• By reading from the side of the burette

• By reading from any point on the meniscus

• By reading from the bottom of the meniscus

What should you do if the stopcock of the burette leaks?

• Replace the burette immediately

• Start with water to check for leaks

• Ignore it and continue the experiment

• Use a different indicator

Why is it important to perform a rough titration first?

• To save time by skipping the precise titration

• To get an estimate of the equivalence point

• To use up excess reagents

• To avoid using an indicator

Why is it important to perform multiple titrations?

• To obtain a more accurate average concentration

• To ensure the solution is fully neutralized

• To practice the titration technique

• To use up all the reagents
