Midterm Flashcards
do not breathe vapors; avoid contact with skin and eyes
irritant
wear safety goggles; avoid contact with skin, eyes, or clothing
corrosive
keep chemical away from contact with skin, eyes, or clothing; avoid mixing with other chemicals unless directed
oxidizing agent
keep chemical away from heat, sparks, or flames; keep container closed when not in use
flammable
avoid all contact with the body; avoid inhalation, swallowing, or contact with skin (especially broken skin)
toxic
open bottle in the fume hood; avoid contact with eyes and skin
Lachrymator (causes tears to form)
Use extreme care when using or handling; avoid all contact with the skin, eyes, and lungs
carcinogen
keep container tightly capped; recap immediately after sue
hygroscopic (absorbs water)
keep container tightly capped; recap immediately after use; do not let chemical sit out in the air - use quickly
moisture sensitive
if chemical is on skin or eyes
flush with water for 15 minutes
ability of a solid or gas to dissolve in a liquid
solubility
the solution that does the dissolving
solvent
the substance being dissolved
solute
what kind of property is solubility
chemical
if two liquids mix completely
miscible
density (physical property)
mass/volume
percent yield
actual/theoretical * 100
a method to analyze how much analyte (species of interest) is present
titration
a species that changes colors at different pH
acid-base indicator
method of determining the concentration of the titrant by using a known amount of a standard compound
standardization
a portion of the standard
aliquot
the reactant which is completely consumed or “used up” during the reaction, so calculations are based upon the moles of the limiting reagent
limiting reagent
Dalton’s Law (Patm)
Patm = P02 + PH2O
Ideal gas Law
PV = nRT
