Mole Ratios and Reaction Stoichiometry
Reaction A: Sodium Bicarbonate and Hydrochloric Acid
Experimental Data
(a) Mass of evaporating dish + watch glass
(b) Mass of evaporating dish + watch glass + sodium bicarbonate
(c) Mass of sodium bicarbonate used
(d) Mass of evaporating dish + watch glass + sodium chloride
(e) Mass of sodium chloride collected (experimental yield)
Data Analysis
1) Use your data to determine the experimental mole-to-mole ratio between sodium bicarbonate and sodium
chloride. Show your work for each step.
• Convert the mass of sodium bicarbonate used to moles.
• Convert the mass of sodium chloride collected to moles.
• Divide both of your results from the preceding two steps by the lower mole value to determine the simplest
mole-to-mole ratio between sodium bicarbonate and sodium chloride.
