Question

Rank the following from most acidic to least acidic. Rank these items from most acidic to least acidic. To rank items as equivalent, overlap them.____

Answer 1

The compounds, ranked from most acidic to least acidic, are H2SO4, NH4NO3, NaCN, NaOH, NaCl.

Step-by-step explanation:

Ranking of the compounds from most acidic to least acidic:

• H₂SO4
• NH4NO3
• NaCN
• NaOH
• NaCl

Acidity is determined by the presence of hydrogen ions (H+). Compounds that release more hydrogen ions are more acidic. In this case, H₂SO4 is the most acidic because it is a strong acid that completely dissociates in water, releasing two hydrogen ions. NH4NO3 is less acidic because it partially dissociates, releasing one hydrogen ion. NaCN is even less acidic because it does not dissociate as much, releasing only a small number of hydrogen ions. NaOH and NaCl are not acidic at all; in fact, they are basic because they release hydroxide ions (OH-) instead of hydrogen ions.
