Question

1- What information will you obtain in this experiment that will allow you to calculate the number of moles of calcium concumed>

2- What information in this experiment will you obtain in this experiment that will allow you to calculate the number of moles of hydroxide produced through the reaction of Ca and water?

3- What algebraic equation allows us to find the number of moles of hydrochloric acid added during the titration from its volume and concentration? Remember, the symbol M (for molarity) is equivalent to mols/L.

Answer 1

1. The information that allow to obtained the number of moles of calcium consumed is the volume and concentration of titrant added from the burret.

2. The information that allow to obtained the number of moles of hydroxide produced through the reaction of Ca and water is the volume and concentration of an acid reactant Ca(OH)₂ is itself a base.

3. The algebraic equation allows us to find the number of moles of hydrochloric acid added during the titration from its volume and concentration is

No. of moles = Volume(L) * Concentration (M)
