Question

In an experiment you are performing, you are

told to measure out 2.3 grams of one reactant

and 4.5 grams of the other reactant. You

measure the exact amount of each substance

and put each in a separate beaker. The

procedures ask you to use Deionized pure

water to dissolve each of the reactants with

Next, you are told to pour one of the dissolved

reactants into the other and watch as the

reaction occurs creating a solid precipitate. To

measure the amount of precipitate/product

made, you must filter that solid using a funnel

and filter paper. You notice that there is a slight

tear in the filter paper and some solid moving

into the beaker below the filter funnel. When

the liquid completely filters away and you

measure the solid precipitate, do you expect

the percent yield of the experiment to be

higher or lower than 100% and Why?

Answer 1

lower than 100%

Step-by-step explanation:

Percent yield is the percent ratio of actual yield to the theoretical yield. It is calculated to be the experimental yield divided by theoretical yield multiplied by 100%(ThoughtCo). The percentage yield shows how much product is obtained compared to the maximum possible mass(BBC).

Since there was a hole in the filter paper from which some solid returned to the beaker, the mass measured as the actual yield of the reaction is less than what it should be thereby lowering the percent yield less than 100%.
