Chemistry crossword
Clues across and down, at three difficulties, and it prints with the answer key.
Across
- 4 Base that turns litmus blue
- 6 Two or more atoms bonded together
- 8 Solid dissolved in a liquid
- 11 Table seasoning, chemically sodium chloride
- 12 Glass vessel for mixing in the lab
- 14 Metal that rusts, symbol Fe
Down
- 1 Sour substance with a low pH
- 2 Speeds a reaction without being used up
- 3 Paper that tests for acidity
- 5 Negatively charged particle orbiting a nucleus

About Chemistry
Chemistry keeps track of what matter is made of and how it rearranges. Every substance on this sheet fits somewhere in that accounting: helium and carbon are elements, salt is a compound built from bonded atoms, and a solution is one substance dissolved evenly in another. Litmus paper turns red in acid and blue in base, giving a quick reading without instruments. A catalyst speeds a reaction along while emerging unchanged, which is why small amounts do so much work.
Reach for this when a science class has finished a unit on elements, bonding, and acids and needs the vocabulary recalled rather than reread.
