Romashka-Z-Leto [24]

Answer:

Presence of impurities in the product.

Explanation:

Laboratory experience has shown that the percent yield obtained from a reaction may be greater than 100% if the product obtained from the reaction contains impurities that causes its mass to be greater than it actually would be if the product was pure.

A typical impurity that may be present in a product is the solvent used. This can be removed by evaporation of the solvent or by washing the product thoroughly.

Reaction of solid products with gases may also increase the percentage yield above 100%.

A student titrates a solution containing 0.050 moles of calcium hydroxide with phosphoric acid. How many moles of phosphoric aci
lina2011 [118]

Answer:

The answer to your question is 0.33 moles of H₃PO₄

Explanation:

Data

moles of Ca(OH)₂ = 0.050

moles of H₃PO₄ = ?

Process

1.- Write the balanced chemical equation

           3Ca(OH)₂  +  2H₃PO₄    ⇒   Ca₃(PO₄)₂   +   6H₂O

             Reactants        Elements       Products

                    3                      Ca                     3

                   12                       H                     12

                   14                      O                      14

2.- Calculate the moles of phosphoric acid

      3 moles of calcium hydroxide --------------- 2 moles of phosphoric acid

      0.5 moles of calcium hydroxide -----------   x

      x = (0.5 x 2)/3

      x = 0.33 moles
