Accurate titres within 0.10 cm3 of each other are known as being .
|
What is the effect on the titre if the pipette used to transfer the standard solution to the conical flask has an air bubble inside?
the titre will be higher than the actual value
the titre cannot be determined
the titre will be unaffected
the titre will be lower than the actual value
|
What is the effect on the titre if all burette readings are taken from the top of the meniscus instead of the bottom?
the titre will be higher than the actual value
the titre will be lower than the actual value
the titre cannot be determined
the titre will be unaffected
|
What is the effect on the titre if the volumetric flask used to prepare the standard solution for the conical flask is filled with water above the graduation line and this standard solution ?
the titre will be lower than the actual value
the titre cannot be determined
the titre will be unaffected
the titre will be higher than the actual value
|
What is the purpose of repeating the titration until two accurate titres are concordant?
to ensure accuracy in measuring the volume
to prevent the solution from becoming too dilute
to mix the two solutions thoroughly
to improve the precision of the results
|
What is the purpose of running the solution in the burette into the solution in the conical flask while swirling?
to ensure accuracy in measuring the volume
to mix the two solutions thoroughly
to determine the end point of the titration
to prevent the solution from becoming too dilute
|
What is the purpose of adding an indicator to the solution in the conical flask during an acid-base titration?
to determine the end point of the titration
to increase the reaction rate
to measure the volume of the solution
to neutralise the solution
|
What is the purpose of inverting the volumetric flask several times after filling it with a standard solution?
to mix the solution thoroughly
to prevent the solution from becoming too dilute
to ensure accuracy in measuring the volume
