Structure of Nitric Oxide
Imagine Nitric Oxide as a tiny but mighty molecule made up of just two atoms: one nitrogen (N) and one oxygen (O). These two atoms form a bond, linking them together like best friends holding hands. This bond is special because it shares an odd number of electrons, making Nitric Oxide a bit unique compared to other molecules. This uniqueness gives Nitric Oxide the ability to perform important jobs in our bodies, like helping our blood vessels relax to improve blood flow. Picture it as a tiny messenger, darting around in our system, ensuring everything runs smoothly. Nitric Oxide may be small, but its impact on our health and the environment is huge!
Preparation of Nitric Oxide
Making Nitric Oxide (NO) in a lab might sound like a wizard’s potion, but it’s actually a pretty straightforward process! To create this interesting gas, scientists use a simple reaction that involves combining two common substances: copper (Cu) and nitric acid (HNO₃). When these two are mixed, a chemical reaction happens that produces Nitric Oxide gas, water (H₂O), and another substance called copper(II) nitrate (Cu(NO₃)₂). The reaction looks something like this in the world of chemistry:
In simpler terms, when copper and nitric acid get together, they transform, creating Nitric Oxide along with water and copper nitrate. It’s like a magic trick where three ingredients go in, and three totally different things come out! Nitric Oxide is then collected for scientists to study or use in various ways, showing us how a simple reaction can lead to the creation of something as fascinating as NO.
Nitric Oxide in Foods
- Beets: These red and earthy veggies are champions at increasing Nitric Oxide levels. They contain nitrates, which your body turns into Nitric Oxide.
- Garlic: Not only is garlic great for flavoring your food, but it also helps your body create more Nitric Oxide. It encourages your blood vessels to relax and improve circulation.
- Leafy Greens: Spinach, kale, and arugula are full of nitrates, just like beets. Eating them can help pump up your Nitric Oxide levels.
- Citrus Fruits: Oranges, lemons, and limes are packed with vitamin C, which works wonders in preserving your Nitric Oxide levels and keeping your blood vessels healthy.
- Nuts and Seeds: Almonds, walnuts, and seeds like flaxseeds are loaded with amino acids that your body uses to make Nitric Oxide. Plus, they’re a tasty snack!
- Watermelon: This juicy fruit contains L-citrulline, an amino acid that gets converted into another amino acid (L-arginine) in your body, which then helps produce Nitric Oxide

Chemical Properties of Nitric Oxide
Combines with Oxygen
Nitric Oxide loves to join forces with oxygen. When it does, it forms nitrogen dioxide (NO2), a brown gas. This reaction is important in the atmosphere and can affect air quality.
- Equation: 2 NO + O₂ → 2 NO₂
Reacts with Ozone
NO also reacts with ozone (O₃) in the air. This reaction helps control the level of ozone near the Earth’s surface, which is good because too much ozone down here can be harmful.
- Equation: NO + O₃ → NO₂ + O₂
Forms Nitric Acid in Air
When mixed with water in the air, NO can turn into nitric acid (HNO₃). This is one way acid rain can form, showing how NO’s reactions can have environmental impacts.
- Equation: 2 NO₂ + H₂O → HNO₃ + HNO₂
Reacts with Alkalis
NO reacts with alkaline solutions to form nitrites (NO₂⁻). This reaction is a cool example of how NO can change when it meets different substances.
- Equation: 2 NO + 2 NaOH → 2 NaNO₂ + H₂O
