Lab Exam (Chem 1020)
Mass - answer the amount of matter in the object
weight - answer the force of gravity on the object
volume - answer length in three dimensions
accuracy - answer how close a measurement is to the true value
precision - answer how close the measurements are to one another
acid - answer something that produces hydrogen ions (or protons) in a solution
base - answer something that produces hydroxide ions in a solution
monoprotic acid - answer donates one proton (or hydrogen atom) in solution
diprotic acid - answerdonates two protons
triprotic acid - answerdonates three protons
indicator - answera dye whose color depends on the acidity of the solution it is in
hydrate - answeran ionic compound that contains a specific number of water molecules
for each formula unit
Law of Definite Proportions - answera compound is always made up of the same
relative masses of the elements that compose it
Hydrate - answerionic compound that has water as an integral part of its molecular
structure
limiting reactant - answerdetermines the maximum amount of product that can be
formed (the theoretical yield)
mass (g)/volume (mL) - answerDensity
(Actual/theoretical) x 100% - answerPercent Yield
precipitate - answermixing two clear solutions containing dissolved ionic reactants
results in the formation of a solid product insoluble in water
