Hint 1. How to approach the problemConsider the reactionand react in a 1:1 ratio. You should find the number of millimoles of each that you have, then determine whether any acid or base is leftover after the two compounds react.
Hint 2. Calculate the amount of acidMolarity is defined as the number of moles per liter, or millimoles per milliliter. Thus one has the relationUsing millimoles (instead of moles) in titration calculations will often cut down on the amount of unit conversion.How many millimoles of are in 100. of 0.200
?
Express your answer numerically.
Calculate the amount of baseMolarity is equal to moles per liter, or millimoles per milliliter. Thus you can use the relationUsing millimoles (instead of moles) in titration calculations will often cut down on the amount of unit conversion.How many millimoles of are in 50.0 of 0.250
?
Express your answer numerically.
Determine the amount of leftover acidHow much is leftover after the 20.0 of reacts with the 12.5 Express your answer in units of millimoles.
