26
titration purpose
to determine the concentration of a substance by reacting that substance with another substance of known concentration in a reaction
27
neutralization
write balance equation
convert to mols of given
L(mol/L)=mol
use mol bridge
convert mols to grams
28
limiting reactant
write balanced equation
determine limiting reactant
gram ->mol->mol bridge =smaller value
find grams of product (using excess reactant mols)
