Question 26

titration purpose

Answer 26

to determine the concentration of a substance by reacting that substance with another substance of known concentration in a reaction

Question 27

neutralization

Answer 27

write balance equation
convert to mols of given
L(mol/L)=mol
use mol bridge
convert mols to grams
