Equivalence Point
Definition
The equivalence point in a titration is when exactly enough titrant has been added to react completely with the substance being analyzed.
Analogy
Imagine you're baking cookies and you need exactly one cup of sugar. When you've poured out exactly one cup, that's your equivalence point - any more or less would throw off your recipe!
Related terms
Titrant: The solution with known concentration used in titration. It's like our measuring cup for sugar in cookie baking analogy!
Analyte: The substance whose concentration is being determined during titration. In our cookie analogy, this would be equivalent to knowing how sweet your cookies are going to be based on how much sugar you add.
Molar Concentration (Molarity): This refers to the amount of solute (in moles) divided by total volume (in liters) of solution. It’s like knowing how many cups of sugar are needed per batch of cookies.
