Why is blank titration necessary in the mohr method?
AS silver ions first react with Cloride ions in the sample(equivalence point) and when all the chloride ions are consumed we have to add more silver nitrate solution to increase its concentration to a level where it can precipitate chromate ions as silver chromate precipites (reddish brown ppts) this is the end point . so remove this error of equivalence point detection we take the same volume of indicator (chromate solution) in a flask labelled blank and add water into this flask (the same volume as that of sample solution) and then titrate this blank labelled flask with standard silver nitrate solution and note the volume of titrant consumed (blank volume),then calculations for real equivalence point can be made as: equivalence point=(end point)-(blank volume)
What happens if the tip of the burette is not filled before the titration begins?
The measure of volume used in the titration will be inaccurate, because there will appear to be more titrate used than has actually been dispensed.
What is ultrasonic titration?
Titration involves measuring the quantity of a liquid necessary to convert a volume of a substance to a different form. By applying ultrasonic waves to the substance and seeing if its structure changes, researchers can gain more precise readings.
What is gravimetric titration?
A titration in which the mass of the titrant is measured instead of the volume. Then you can express moles of reagent/ kg of titrant as it's concentration. How convenient. They are more accurate and precise because on most analytical scales you can measure out four or more decimal places. Where as in pipettes and burets you can only measure two.
How do you explain the volume of liquid remaining when the egg was removed from the syrup?
The measured volume decreases by the volume of the egg. However, the volume of just the liquid never changes.Read more: What_is_the_volume_of_liquid_remaining_when_the_egg_is_removed_from_the_syrup

What does 86 percent alcohol mean?
It means that either 86% of the weight is alcohol, or 86% of the volume. Volume is more standard, I believe.It means that either 86% of the weight is alcohol, or 86% of the volume.

Does the more displaced liquid more buoyant?
Buoyant force = volume x density x acceleration due to gravity So more the volume greater the buoyant force ___________________________________ The volume above must be volume of liquid displaced, not the volume of the object placed in the liquid.
How is the volume of a cone changed if the the radius is doubled?
the is more volume in the cone
Does shouting have more volume than whispering?
The gas in volume has more space by the louder u do it
Which has more volume -- a kilogram of gold or a kilogram of aluminum?
1 kg of aluminum has more volume.
Does the volume of a cell grow more or less rapidly than the surface area?
volume increases faster than the surface area.
Is the volume variance a controllable variance from a spending point of view?
No, the volume variance is controllable but not related to spending. The volume variance calculates the dollar impact of producing more or less than the budgeted production volume.
