Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the context-dependent calculation?Equivalent weight varies based on the specific chemical reaction (acid-base, redox, etc.)
2. What is the historical significance?Formed the basis for early quantitative chemistry and the law of equivalents
3. What is equivalent weight in chemistry?Equivalent weight is the mass of a substance that reacts with a fixed amount of another substance, like hydrogen or oxygen.
4. Why do chemists use equivalent weight instead of just mass?It tells how much of a substance will combine or replace another, making it easier to predict reactions.

Normality: A measure of concentration equal to the number of equivalents of solute per liter of solution.
Electrochemistry: The branch of chemistry concerned with the relationship between electricity and chemical reactions.
Stoichiometric Factor: The number of reactive units (e.g., H+ ions, electrons) involved in a specific chemical reaction per molecule.
