Yield - GCSE Chemistry Definition

In GCSE Chemistry, "yield" refers to the amount of product you get from a chemical reaction compared to the amount you are expected to get. It is often shown as a percentage called the "percentage yield." To find the percentage yield, you compare the actual amount you got (the actual yield) with the maximum amount you could have got if everything worked perfectly (the theoretical yield). This helps us understand how efficient a reaction is. Sometimes, not all the reactants turn into products because of things like incomplete reactions, wasted substances, or measurement errors, which is why the percentage yield is rarely 100%. Imagine you follow a recipe that says you should get 24 cookies from the dough you make. After baking, you count only 20 cookies, so the percentage yield is 83.3%.
