Final answer:
NH4NO3, or ammonium nitrate, is acidic because it originates from a weak base and a strong acid. This causes it to release protons into solution, increasing the acidity. Examples with their pH values show human blood is slightly basic, household ammonia is basic, and cherries are acidic.
Step-by-step explanation:
The compound HONH₃NO₃, which seems to represent a typo and should likely be NH₄NO₃ (ammonium nitrate), is acidic. This is because it is formed from the reaction of a weak base (NH₃OH, ammonia in water) with a strong acid (HNO₃, nitric acid). In the case of ammonium nitrate, NH₄NO₃, the NH₄+ ion can release a proton to form NH₃ and a hydrogen ion, making the solution acidic.
As for examples of substances and their pH values to identify them as acidic, basic, or neutral:
- Human blood, with a pH of 7.4, is slightly basic.
- Household ammonia, with a pH of 11.0, is basic.
- Cherries, with a pH of 3.6, are acidic.
Furthermore, if we look at an example like NaOH (sodium hydroxide), it is a strong base. Conversely, H₂SO₄ (sulfuric acid) is identified as a strong acid. When arranging solutions from most acidic to basic, it would go as follows: H₂SO₄ (most acidic), NH₄NO₃, NaCl (neutral), NaCN, NaOH (most basic).
