Question

The percent yield of a chemical reaction is valuable to many industries. Low percent yields can result in the loss of large amounts of money. Which of the following would likely increase the percent yield of a reaction?

Check all that apply.

using accurate measurements

using pure chemicals

performing the reaction under the most ideal conditions

adding water to the experiment

Answer 1

Select: using accurate measurements; using pure chemicals; performing the reaction under the most ideal conditions.

Reasoning: accurate measurements and pure reagents reduce losses and side reactions and ensure you start with the correct stoichiometry, and ideal conditions (temperature, pressure, catalysts, etc.) maximize conversion. Adding water is not generally helpful unless the reaction specifically requires water — it can dilute reactants or cause side reactions and often lowers yield.
