Mississippi Science PHS.3.4
The Standard
- PHS.3
- Students will analyze the organization of the periodic table of elements to predict atomic interactions.
Use naming conventions to name common acids and common compounds used in classroom labs (e.g., sodium bicarbonate (baking soda), NaHCO3; hydrochloric acid, HCl; sulfuric acid, H2SO4; acetic acid (vinegar), HC2H3O2; and nitric acid, HNO3).

What This Standard Means
What Students Need to Do
- Students read formulas and name common lab acids and compounds. They connect household names, such as baking soda and vinegar, to the chemicals used in labs.
What Mastery Looks Like
- A student names HCl(aq) as hydrochloric acid, HNO3(aq) as nitric acid, and NaHCO3 as sodium bicarbonate. They know vinegar contains acetic acid rather than being pure acetic acid.
Common Misconceptions
- Students may call HCl(aq) hydrogen chloride instead of hydrochloric acid. They may treat NaHCO3 as an acid because its formula contains H, or assume vinegar is pure acetic acid.
How to Assess It
- Exit ticket: Write the lab names for HCl(aq), H2SO4(aq), and NaHCO3. Then circle the name also used for baking soda.

Ways to Teach It
Give pairs cards for vinegar, baking soda, acetic acid, sodium bicarbonate, and their formulas; have them build matching sets.
Ask: Why is HNO3 named nitric acid, while NaNO3 is sodium nitrate? Have students write two sentences using the word nitrate.
Play a matching round with formula cards for HCl, H2SO4, HNO3, and NaHCO3 and separate name cards.
Have students compare a vinegar bottle and baking soda box, then label each product as a mixture or a compound.
