Titration and Acid Concentration Quiz

What is the purpose of using a pipet in the titration process?

• To observe the color change during titration

• To mix the acid and alkali thoroughly

• To add a precise amount of acid to the conical flask

• To measure the exact volume of alkali

Why is an indicator like phenolphthalein used during titration?

• To neutralize the acid

• To signal the endpoint of the titration

• To measure the volume of acid

• To speed up the reaction

What is the purpose of performing a rough titration before an accurate one?

• To ensure the acid is completely neutralized

• To estimate the endpoint for more precise measurements

• To save time

• To use less alkali

How is the concentration of the acid calculated after titration?

• By dividing the volume of alkali by the volume of acid

• By multiplying the number of moles of alkali by the volume of acid

• By dividing the number of moles of acid by the volume of the acid sample

• By adding the volumes of acid and alkali

What is the relationship between the moles of alkali and acid in the titration process?

• 2 moles of alkali neutralize 1 mole of acid

• 1 mole of alkali neutralizes 2 moles of acid

• 1 mole of alkali neutralizes 1 mole of acid

• 1 mole of alkali neutralizes 0.5 moles of acid
