Question Video: Matching the Given Acids and Bases with Their Chemical Formulas Science

Video Transcript

Which row in the diagram shows the labels with the correct chemical formula for the name? (A) Row one, (B) row two, (C) row three, (D) row four, or (E) row five.

We have been given four chemical names: hydrochloric acid, sulfuric acid, potassium hydroxide, and nitric acid. We have to match the correct chemical formula to these names. The names themselves can help us decipher the correct formulas.

The “chloric” part of “hydrochloric” indicates the presence of chlorine. Therefore, the correct chemical formula for hydrochloric acid is HCl. The name “sulfuric” indicates that sulfur will be present. Therefore, the chemical formula of sulfuric acid is H2SO4. The chemical symbol for potassium is K and hydroxide is OH. Therefore, the correct formula is KOH. The word “nitric” indicates the presence of nitrogen. Therefore, the chemical formula of nitric acid is HNO3.

The only row that shows the labels with the correct chemical formula for the name is row two. Therefore, the answer is (B), row two.
