chapter 2: Tools of Trade Flashcards
what is readability
the smallest increment of mass that can be indicated
what is a microblanace
measures milligram quantities with a readability of 1microgram
what is the linearity error
max error that can error as a result of nonlinear balance response
what is buoyancy
the upward force exerted on an objector gaseous fluid
what is the equation for relative uncertainty
uncertainty in quantity/ magnitude of quantity x100
what is a autotitrator
delivers reagent from a reservoir bottle
what can be measured more precicely
mass more than volyme
if you have a larger volumetric flask what does it mean
the smaller the realtive uncertainty
what is a pipet
glassware calibrated to deliver a known volume of a solution at 20 degrees
what is a serial dilution
process of making successive dilutions to obtain a desired concentration of reagent
what is calibration
the process of measuring the actual quantity that corresponds to an indicated quantity on the scale of the instrument
how do we get greater accuracy for calibrating volumetric glassware
measure volumes associated with a particular piece of equipment
what is the equation for correction for thermal expansion
cā/d/ = c/d
