Chemical Formula Writing Worksheet #2
Write chemical formulas for the compounds in each box. The names are found by finding
the intersection between the cations and anions. Example: The first box is the
intersection between the “zinc” cation and the “chloride” anion, so you should write
“ZnCl2”, as shown.
chloride
zinc
ZnCl2
iron (II)
iron (III)
gallium
silver
lead (IV)
acetate
nitrate
oxide
nitride
sulfate
1) silver carbonate
2) potassium hydrogen phosphate
3) aluminum hydroxide
4) sodium hydrogen carbonate
5) calcium acetate
6) potassium permanaganate
7) calcium perchlorate
8) lithium carbonate
9) magnesium hydrogen sulfite

10) sodium hypochlorite
These formulas involve the use of a polyatomic ion. The cations are all of variable
oxidation state, so Roman numerals are needed.
Write the correct formula for:
11) tin(IV) chlorite
12) mercury(II) phosphate
13) tin(II) carbonate
14) mercurous acetate
15) lead(II) chromate
16) copper(I) sulfite
17) stannous dichromate
18) iron(III) nitrate
19) ferric sulfate
20) ferrous hydroxide
